The French Savoir Faire

Salon owner

Salon ownerThe owner, Patou Castay, has 35 years of experience in the field of hair and has expertise with all hair types and textures as a trichologist, stylist and colorist. In the 80s, Patou opened her first salon in partnership with a holistic medical center where she saw first hand the negative impact that certain chemicals have on one’s health. She was already aware of the allergic reactions caused by certain hair dyes, relaxers, and permanent waves.

As a trichologist she had treated many cases of hair loss and scalp disorders. The answer was to find safer, less aggressive, “greener” alternatives than the traditional salon chemicals.

Because of her biochemistry background in her native France, Patou was able to navigate all the confusing product labels, misleading ingredient lists, and false claims found in the cosmetic industry. She selected professional products that were “green” enough to be safe, non-toxic, and eco-friendly but also capable of delivering the expected results without which she would be ecologically correct but with no clients.


Salon ownerNatural Hair Coloring

Our extensive European organic color lines are hypo-allergenic and free of irritants (no ammonia, PPD, resorcinol, or formaldehyde), yet they cover 100% of gray hair and deliver beautiful, long lasting, realistic tones. Since the hair and skin are not chemically "attacked", the new growth blends with the processed hair, therefore avoiding unnatural contrasting roots. Stains along the hairline are also no longer an issue.


Natural Hair Relaxer/Texturizer

Our cream relaxers, although not organic, contain no lye, have minimal amounts of chemicals and a low alkaline PH. Acidic liquid protein, natural oils, and plant extracts are added to the formulation to increase the strength, moisture, and elasticity of the hair fiber, to safeguard the integrity of the scalp, and to maintain the cortex and the cuticle in optimum health. Each batch of relaxers is custom made according to the degree of curl elongation that you wish to obtain.

Salon ownerFirst example:

Your hair is tightly coiled, difficult and time-consuming to comb and style. You sometimes wear braids, twists, and ponytails, but you would also enjoy wearing your curls in a carefree, loose style if you hair were more manageable. In this case, a minimum amount of texturizing would loosen up some of the tightness, facilitate detangling, and reduce the amount of time and products necessary to achieve a better ringlet definition less prone to mat or snarl together.

Second example:

Your hair is loosely coiled and you like wearing it straight, silky, and bouncy. After undergoing all the heat involved in obtaining that look, you find that your hair reverts to its original state with the least amount of perspiration or humidity. In this case, a greater amount of curl relaxation is needed to cut down on the intensity or frequency of heat styling and to prevent early reversion.

Natural Treatment for Curly Hair

For temporary curl and frizz reduction using keratin protein, and heat, the Brazilian smoothing treatments are very efficient. Unfortunately, it is the formaldehyde and its hidden derivatives contained in the formula which give the desired results. To hear an honest opinion on this very controversial subject, consult with Patou and find out if your hair type qualifies for the new milder, non chemical keratin treatments.

And for the purist who wishes to remain 100% natural with NO chemical exposure whatsoever but who needs help caring for sometimes dry, brittle, dull, “snarly” tresses, we recommend trying our high performing trichology salon treatments.


Now you are in control of your hair; your hair is not in control of you!

Trichology, the Science of Hair

Patou Castay is one of the few hair experts in the United States who is certified as a trichologist by the International Association of Trichologists (IAT). She has been a guest speaker on numerous television and radio programs as well as a lecturer at various health and beauty shows.

Long recognized as a science in England, trichology is the study of the hair and scalp, just as dermatology is the study of skin. The London Institute of Trichology was established in 1902 to advance the understanding of hair and scalp science. Since then, trichology has spread to other countries, with a growing number of certified practitioners.

Trichologists are fully qualified to treat such hair and scalp problems as hair loss, dandruff, itchiness, hair breakage, oiliness, dryness, chemical allergies, etc.

Salon ownerPatou’s approach to treating those conditions is also holistic and natural. It may consist of applying specific therapeutic formulations to the hair and scalp in conjunction with massage, heat, steam, or laser. Those remedies in the form of ointments, masks, oils, mineral or vegetal extracts have healing properties which exfoliate, detoxify, purify, soothe, hydrate, and reconstruct. However, certain cases of hair loss and dandruff require the use of more potent medicinal compounds. The trichology consultation, which includes a review of personal history and an examination of the hair and scalp, will determine the best suited treatments for the client. In some instances, referral to a dermatologist is recommended. Hair is a reflection of your health. So, nutritional advice and food supplements might be recommended. With thousands of hair products on the market, finding the right one that will work for you is no easy task. Let the trichologist evaluate your existing regimen by bringing your own products to the consultation and let her prescribe new formulations if necessary.
