This hair growth inhibitor spray from Skin Doctors is made from natural herbal extracts and aims to reduce hair re-growth by starving the hair of nutrients.

What are Hair Growth Inhibitors?

Hair growth inhibitors are not depilatories, which are designed to actually remove hair, but are simply to slow down re-growth after hair removal by other methods.

The aim of hair growth inhibitors is to reduce the frequency of your hair removal sessions by increasing the time in between, whilst also causing lighter, finer re-growth.

Hair growth follows 3 stages;  the growth stage (Anagen), transitional stage (Catagen) and resting stage(Telogen).

Stages of hair growth

The 3 stages of hair growth

At any one time, hair all over the body is at varying growth stages, and hair growth inhibitors are only effective on hairs that are in the actively growing, Anagen stage.

For this reason, hair growth inhibitors will require regular use over several weeks and months to show positive results.

Who Can Use the Product

Skin Doctors hair no more can be used by both men and women.

It is suitable for all skin and hair types, although you may find that it will take longer to achieve noticeable results if your hair is thick and dense.

Generally the effects are seen more quickly on areas with lighter, finer hair.

Where Can it be Used

This product can be used on all parts of the body and for facial hair.

How quickly and efficiently the product will work depends on the area being treated - as stated previously, areas of thicker, coarser hair will be likely to take longer.

It is important to remember that you will need to apply the product diligently for a lengthy period for best results.

You should always carry out a small patch test prior to full use.

How to Use it

Carry out the patch test 24 hours prior to use and if there is no irritation, you can go ahead with the full treatment.

Firstly, you will need to remove hair from the treatment area using your usual method.

The best results are achieved if you use a method that involves pulling the hair from the root, such as waxing, tweezing, epilating etc.  However, you can also shave, if this is your preference.

Following hair removal, lightly spray the area with Skin Doctors hair no more and massage gently into the skin until it is fully absorbed.

Thereafter you will need to continue to spray the area every day, and after every hair removal session.

When you are satisfied with the results you will still need to use the product 2 - 4 times weekly to maintain.

How Effective is it? - The Evidence

To try to determine the efficacy of this product, firstly I took a closer look at the ingredients and secondly, at the available feedback and reviews:

Pilinhib Veg

The main components of Pilinhib Veg are:

Urea is a humectant, that is to say it retains or preserves moisture, and is found as a natural component in the surface layer of the skin, to keep it hydrated.

When topically applied to the skin it increases its capacity to hold moisture, whilst reducing the amount lost.

Urea has also been found to increase the skin's ability to absorb some skin care ingredients so that they can penetrate the epidermis more easily.

Salicylic Acid was originally obtained from the bark of the willow tree, but is now produced synthetically.

Salicylic acid, in sufficient quanitity, can prevent pores from clogging by slowing the shedding of cells inside hair follicles, and may help to break down keratin, which is a protein found in skin and hair.

It also has a slight antiseptic effect.

Other ingredients such as Hamamelis, Arnica, Hypericum, Menthol and Soy act have astringent, soothing, healing and softening properties.

Efficacy Test

I found the results of a clinical study conducted to determine the effect of a gel containing 5% Pilinhib Veg on the re-growth of hair, following removal by shaving.

The test concluded that the gel had a significant effect on hair regrowth on legs, compared to a placebo.

However, it was very small, comprising just 10 participants (all female) who carried out leg treatments twice daily for 3 weeks with a placebo gel on one side and the treatment gel on the other.

I would say that this is far from conclusive evidence, but does give an indication that the substance may be effective for some individuals under some circumstances.

Reviews and Feedback

Having examined the available reviews, comments and feedback, I have found that it more or less bears out what I have already concluded.

There is no doubt that some individuals swear by Skin Doctors hair no more and are very happy with the results, whilst for others it appears to have little or no effect.

My one caviat to that is; whatever the circumstances, it will require time, regular treatments and patience to see any noticeable reduction in hair re-growth and it may be that some individuals do not feel that the benefit is worth the time and effort involved. 


​How long will it take to see results?

The results will vary depending on the individual and their hair growth patterns, the thickness of the hair, the amount being removed and how often you use the product.

Does it remove the hair?

No, Skin Doctors hair no more is a hair growth inhibitor - designed to slow growth after hair removal by another method.

Is hair no more permanent?

No - you will need to continue to use the product to maintain results.

Can it be used anywhere?

Yes, on any part of the body or face where you usually remove hair.  Do carry out a patch test, especially on sensitive area, prior to use.  To use near the eyes, spray onto fingertips and then carefully massage into the area.

Can it be used on black skin?

Yes, the product is suitable for all hair and skin types.

Does it cause ingrown hairs?

No - if anything it may help prevent them

Can I use moisturizers and cosmetics with this product?

Yes, apply Skin Doctors hair no more first, and once fully absorbed and dry, you can then use your usual moisturizers, make-up etc.

Is it FDA Approved?

No.  Like all over the counter hair inhibitors, it is not FDA Approved


Unfortunately, I am unable to give any firm guarantee that this product will work for you, although it clearly does have the desired effect for some individuals.

It is, however, relatively inexpensive at around just $13 for a 4.1 fl oz bottle, which should be sufficient to last at least a few weeks (depending on how big the area is and how often it is being treated).

Things we Liked

  • Inexpensive - at only $13 a bottle
  • Easy Application - spray bottle
  • Scent - light and pleasant
  • Use Anywhere - male or female, all over the body
  • Moisturizing

For the past 12 months, I have been testing and playing with all sorts of hair removal products for Hair Free Life. My goal is to provide the most accurate and up-to-date hair removal consumer information on the internet.

    I suffer with PCOS therefore I have excessive hair growth. I have undergone YAG laser treatment for my face however I have now stopped and the hair growth is more frequent. I wanted advice if I should get the StopHair stray or the Skin doctor hair inhibitor spray. I would really appreciate some of your input.

    Your articles are amazing to read and very helpful for people suffering with unwanted hair growth.

    Thank you very much.

      Hi – unfortunately I am unable to really recommend either or choose between them, as the results and tests for both products are very mixed and seem to vary from person to person. In both cases you must appreciate that they only claim to slow hair regrowth and not to stop regrowth completely. You will still need to use a hair removal method and then use the inhibitor daily, long term, to notice results. I am sorry that I am not able to be more specific but sadly, whilst some individuals are very happy with the results of these products, for others they don’t appear to work.
