1. Why do the hairs fall out with an IPL treatment?

The light penetrates the skin and reaches the hair root. The light cannot be conducted any further than the hair root, which is heated along its entire length to about 70 degrees. The hair follicles are damaged and remain permanently closed, preventing any hair regrowing from this root.

Back

2. Why is less energy needed for thick hair?

Thick hair has a larger accessible surface and therefore needs less energy.

Back

3. The device cannot detect light-coloured hairs. Does this mean that these light-coloured hairs will not fall out at all?

Unfortunately, pale red, blond and grey or white hairs cannot be removed permanently, because they contain too little or no melanin and therefore cannot convert the energy into heat.

Back

4. Why is there a yellow and red light?

This is because of the filter. Yellow radiates more light.

Back

5. What is XENON light? How does it differ from laser?

With xenon light, the light affects several sides of the hair root, whereas with a laser it is precisely the skin that is affected by the light.

Back

6. Why can only 4 skin types be treated with Epilux, but many more with IPL?

Epilux has a filter with only 600 NM (skin types 1-4 can be treated in this way). For skin type 5, a higher filter must be used.

Back

7. Why do some patients have a skin reaction, and others not?

To start with, we refer to those coming to us for treatment as clients, not patients. Even though we work in the same way as a doctors' surgery and offer our clients a hygienic and sterile environment, we are not doctors. That is why we take care to use the word 'clients'. Unlike thin hairs, thick hairs absorb more heat because they have a bigger surface area. This extra heat also affects the surrounding skin, and that is why on these areas of skin there may be a reaction in the form of a small lump or pimple.

Back

8. What exactly does Pulse 1 and Pulse 2 mean?

A beam of light is divided up into a series of pulses.

Back

9. What is a joule?

Joule is a physical unit of energy, work and heat.

Back

10. To what extent is the light harmful to the eyes?

In principle, prolonged exposure to the light is harmful to the eyes, and that is why we stress that protective goggles are worn. Not following this advice may produce dryness of the eyes. During longer sessions, we recommend closing the eyes as well as wearing the protective goggles.

Back

11. Why do the hairs regrow after they have fallen out?

There are various causes for this:

Hormonal fluctuations, e.g. among teenagers whose bodies are still developing. Hormonal fluctuations may therefore cause a few new hairs to grow.

Age: up to the age of 30 years the skin has not yet developed all the hereditary hair roots, and so hair roots and hairs can still be formed.

Area of the body: hair growth varies on different parts of the body.

Back

12. Once the hair root and follicle have been destroyed, is that permanent? Or how often does it need to be treated to obtain a permanent result?

Once the hair root has been completely destroyed, the hair will not regrow. If only part of the hair root has been destroyed, thin hairs will regrow. These will be removed during the next treatment.

Back

13. The IPL technology.

Permanent hair removal is based on intense pulse light, or IPL. In the same way that a camera flash works, these pulses are passed over the skin surface of the part of the body being treated and penetrate the skin. The harmless light is then absorbed by melanin, a pigment in the hair follicles, and conducted down to the hair root. At a temperature of between 70 and 74 degrees Celsius the proteins disintegrate and the hair follicle, which is precisely in the development phase, dies.

Back

14. What types of hairs can be treated?

Because of the larger amounts of melanin they contain (the colouring pigment in the hair); dark hairs are the easiest to treat. Grey, white, pale blond and pale red hair contains virtually no melanin.

Back

15. Is the treatment painful?

Many clients compare the feeling to an elastic band pinging on the skin. The darker and larger the number of hairs, the more intense the sensation will be. That is why the first treatment is the most intense.

Back

16. Why are several treatments at intervals necessary?

A distinction can be made between the various growth phases of the hair. Only in the development phase is it possible to destroy the hair root permanently.

Back

17. What should I be aware about before treatment?

• The hair must not be separated from the root for three weeks before treatment

• Do not epilate or wax

• The areas of skin to be treated must be protected against sunlight

• The paler the skin, the more effective the treatment. A tanned skin causes pain

• The hairs must be 2 mm long at the first treatment, so that the thickness of the hairs can be established

Back

18. Side-effects?

Reddening of the skin can occur at the treatment site, which disappears after a maximum of 24 hours.

Back

19. How can facial hair be treated if the client does not or cannot shave the face?

The hairs can be bleached to lighten them, so that the xenon light can penetrate the skin better.

Back

20. What does the abbreviation Medical CE mean?

The CE abbreviation is a standard under EU law for certain products in connection with product assurance. The producer who uses this standard declares that the product has been approved in accordance with the applicable European directives.

The Medical CE adds that the equipment may also be used in medical institutions, which have extremely stringent guidelines.

Back

21. Are there age limits?

Initially, the lower age limit was set at 13 years as manufacturers were unwilling to profit from children. At the request of many parents this lower limit has been abolished.

Reasons: there are children who because of their body or facial hair are ridiculed or bullied at school.

Important: written parental approval is required to treat any clients younger than 18 years.

Back

22. How long before the treatment should the area to be treated not be tanned?

That depends on the colour. Tanned skin may not be treated because of the risk of burning. Tanned skin allows less light to penetrate (protective function) and is therefore a disadvantage when treating with xenon light.

Back

23. Can the skin around the eyes be treated?

NO-HAIR treats almost all the skin around the eyes, with the exception of the skin between the eyelid and eyebrow, because this skin is too thin and sensitive and even with professional treatment the eye may be damaged. The skin covering the eye globe cannot be treated.

Back

24. What is the most sensitive area for men to be treated?

The beard, because the nerve endings converge around the lips.

Back

25. Is the treatment dangerous for cancer patients?

In principle it is not. For safety's sake, however, the client should first ask his or her treating doctor to give written consent to the treatment.

Back

26. How can a treatment with the IPL system lead to burning?

If the guidelines are followed properly, the skin will not burn. Only human error (e.g. forgetting to place the filter before beginning treatment or not taking care that skin is most tanned in the summer) can adversely affect the treatment. It is the responsibility of the treating specialist to treat the client carefully and properly. If burning does occur, a brown crust will appear first on the skin, and when this falls off it reveals a white spot, which can take up to a year to revert to the original colour.

Back

27. Is treatment a risk to diabetic patients?

In principle it is not. Only for patients in the final stages of treatment will it be necessary to ensure that any wounds caused by burning heal properly.

Back

28. Is treatment a risk to pregnant women?

In principle it is not. However, the risk is that if the baby is born prematurely the mother may blame the treatment, and this can result in years of litigation. For this reason, NO-HAIR recommends not treating pregnant women.

Back

29. How can burning be prevented?

• Use enough gel

• Do not push the hand grip and gel

• After treatment, leave plenty of gel on the treated area

• If the skin discolours badly (turns red), apply extra gel and spread it on the skin with a wooden spatula until it covers the entire treated area

• If the redness does not reduce, use cool pads

• After treatment, if the redness is particularly bad, use wound and burn ointment

Back

30. Hair types - a further distinction.

Human hairs are more complex than one would expect at first sight. Even today the mechanisms of hair development, growth and loss are not fully understood, despite major technological advances in recent years. Depending on the shape, three basic types of hair can be distinguished:

Lanugo hairs: the first hairs on the human body, which are developed in the womb. These are short, fine, light hairs, which are replaced at the end of the pregnancy and after the birth by vellus hairs

Vellus hairs: hairs up to a maximum of 2 cm long, which cover the entire body of both men and women and are virtually invisible

Terminal hairs: long hairs with the most pigmentation. We commonly refer to this as 'hair'

Major changes occur as the person reaches sexual maturity, but these affect only certain hairs:

Non-sexual hairs: these hairs are entirely independent of sexual development

Ambisexual hairs: these hairs develop at sexual maturity in the same way with men and women (pubic hair and armpit hair)

Sexual hairs: this hair form actually only occurs with men under the influence of male hormones. Facial hair on the upper lip and chin, but also on the chest, back and legs belongs to this category

Back

31. Causes of hirsutism (excessive hair).

• 90% of cases of excessive hair are due to a genetic predisposition. This means that family history plays a significant role, where relatively high testosterone levels are normal. This occurs more frequently among dark-haired and South European women compared to blond and North European women.

• Another cause is an increased production of the male hormone in the ovaries. This often occurs if there are tumours, or polycystic ovaries. This increases the amount of body hair, and menstruation is reduced or even stops altogether.

• An increase in hormone production in the adrenal glands is often a cause. Here too, tumours and hormonal imbalances can be the reason.

• Disorders of the pituitary gland or hypothalamus can cause hormonal fluctuations.

• Type II diabetes is a possible cause. This form of diabetes occurs mostly as a result of unhealthy eating habits and obesity. Thyroid failure can also cause excessive hair growth.

• In rare cases, a range of medicines may cause excessive hair growth. This must be investigated by the treating doctor.

Back

32. The origins of hair removal.

Pubic hair has been epilated in Europe since the early 18th century, such as at the French court of Louis XV. During the Victorian era in the 2nd half of the 19th century the removal of pubic hair underwent a revival.

Back

33. Hair removal in the 20th and 21st century.

During the early 20th century, the removal of pubic hair in both men and women was fashionable for some sectors of society in Germany. Generally speaking, an increasing acceptance of exposing certain areas of the female body encouraged hair removal. Smaller swimming costumes and more nakedness contributed to the feeling that hairiness was unattractive. Pubic hair is now removed for hygienic, but mainly aesthetic reasons. Women regard body hair in general as unhygienic. Besides cleanliness, body odour also plays a role. Only at the end of the 20th century do we see an increase in the number of men wanting to have hair removed, particularly in the USA. A non-representative survey in a men's magazine concluded that 61% of men remove their pubic hair.

Back

34. What is a papilla?

The papilla is responsible for maintaining the hair. It is found at the base of the hair and provides the main functions such as supplying nutrients to the hair. They are important for hair growth and have therefore been the subject of countless studies into hair growth preparations. The ultimate aim of permanent hair removal is therefore to destroy the papilla.

Back

35. Skin type differences according to Fitzpatrick.

The skin types are divided into 6 different categories according to Fitzpatrick. Skin type 1 is a pale skin type, the other skin types are progressively darker until completely black (type 6).

Back

36. What does hypertrichosis mean?

Hypertrichosis is the term given to excessive hair growth, which is judged according to gender and genetic predisposition.

Back

37. What is the hair root?

The hair root is that part of the hair under the skin surface. The hair follicle surrounds the hair and the root to protect it.

Back

38. What is photorejuvenation?

Photorejuvenation can be used to treat pigmentation irregularities and dilated capillaries, coarsely pored skin and fine wrinkles. IPL equipment is used, making it possible to remove skin changes associated with ageing.

Back

39. What does Pulse Light (PL) mean?

The abbreviation PL stands for pulse light technology. The wavelength of xenon light is reduced using a filter. The depth to which the light penetrates the skin will depend on the wavelength.

Back

40. Phases of hair growth.

1. Anagen phase: the hair follicle is formed

2. Catagen phase: the hair grows. This phase lasts 2 to 4 weeks

3. Exogen phase: the hair is shed from the hair root. If this stage is reached too early, hair loss is the result

4. Telogen phase: resting phase of the hair. This phase can last up to 4 months.

Back

41. What is pulse light?

A method of permanent hair removal. The light is shone at a certain wavelength which allows it to penetrate the skin to the required depth. The energy of the light produces heat which is necessary to destroy the hair structure. This technique can be used for a variety of treatments, such as skin rejuvenation.

Back

42. What is depilation? What is the difference with epilation?

Depilation is short-term, surface hair removal, such as shaving or waxing. With hair removal a distinction is made between temporary and permanent (epilation) hair removal. With epilation (a permanent form of hair removal) tweezers or IPL are used.

Back

43. Can stripes occur during treatment?

Yes, stripes can occur if the hair removal equipment is not used accurately, but can be removed with the next treatment.

Back

44. Can birthmarks also be treated with xenon light?

No, these must be treated by a doctor or specialist. During treatment, birthmarks will be covered with tipp-ex to prevent them from absorbing energy.

Back

45. Is permanent hair removal really permanent?

YES! Once a hair root has been completely destroyed by xenon light the hair cannot regrow. The client must be informed, however, that a single treatment is not enough. NO-HAIR will prescribe an average of six to eight treatments, as only then will all the hair roots be destroyed. As an extra assurance, NO-HAIR offers its clients a guarantee. Not every institution does this, as their equipment is not of a sufficiently high quality. The reasons for hair regrowth are hormonal fluctuations, such as during pregnancy.

Back

46. Can tattooed skin be treated?

No, the skin is too dark in these areas and therefore the light will not penetrate.
