The Hair Strength Shampoo is designed for daily cleansing without stripping the hair of naturally occurring oils. 

The recommended amount of Hair Strength Shampoo is 8 mL per cleanse. The bottle contains 250 mL in total and holds roughly a month’s supply, if cleansing daily. However, it is recommended to adjust the amount used in accordance with hair length, scalp type, and personal preferences.

Sulfates are detergents commonly found in cosmetic and household cleaning products. Sulfates act on the scalp and hair surfaces to remove build-up such as dirt, oil, and other product residues while enabling lather.

Since sulfates are highly effective cleansers and can be great in many cases, some people may experience that they can remove natural oils from the hair and skin. With time, this can result in hair that feels dry, rough, or brittle. Shampoo’s without classical sulfates allow those that experience dryness from sulfates  to wash the hair and scalp more regularly while maintaining shine.

Yes, patch tests were performed under dermatological control on a group of 25 volunteers with normal skin. In the tested group of volunteers there were no irritations or allergic reactions.

Although all our products are dermatologically tested, they are not allergen-free. Eucalyptus oil (limonene) have sensitising properties, meaning they can evoke allergies for certain individuals. It is highly encouraged to check all ingredients before starting to ensure you do not suffer from any allergies of the listed ingredients.
If unsure, perform a patch test before application. To perform a patch test simply apply a small amount of the product onto a clean area of skin on the upper forearm, following 24 hours rinse the area. If any redness, itching, blistering or irritation is observed at any time throughout the test, do not use the product.
