Tested Shampoo and Hair Type Tested On:
The shampoo tested was the Kérastase Specifique Bain Divalent and was applied on very long, light curly hair with a tendency to oil and fall.
The shampoo smelled fresh, but it is not overpowering.
The texture of the product is creamy, non-foaming, and spreads in a buttery way on the hair.
Most common shampoos rely heavily on silicones which have little to no affinity with human skin or hair and are water insoluble, meaning they are very tricky to wash out as they form a layer around the hair shaft, smothering the hair and preventing moisture from penetrating, which will – over time – lead to dryness and brittleness. Yet, it is still used as a main ingredient to most shampoos since it gives your hair added shine and smoothness.
Fortunately, the Bain Divalent shampoo is silicone free. This means no compromise on hair/scalp care especially and hence the “balancing shampoo” attribute mentioned on the label.
Upon using the shampoo, we found it to be gentle on the hair because of its rich creamy-like texture but the non-foaming attribute made it a little difficult to lather and incorporate on a full head of hair (despite increasing the quantity used).
The amount to use depends on hair length: the shorter and/or thinner the hair, the less quantity needed. We left the product on the hair for 2 minutes before rinsing it out. It rinsed out easily and one passage was enough to ensure that no residual amount is left on the hair and scalp. The shampoo was used 3-4 times a week over a period of 3 weeks.
After the first two washes, the hair instantly felt clean, refreshed and nourished. As per the label, the shampoo reduced the oiliness of the roots and strengthened the ends of the hair – particularly if you have very long hair. We specifically noticed that the ends of the hair felt smoother and stronger as they broke less often. The hair looked healthier and more voluminous. No conditioner was used in parallel with the shampoo and we concluded that there is no need for it contrary to other types of shampoos.
Other benefits of this shampoo include 3 main ingredients: calophyllum oil which calms irritation with anti- inflammatory actions, Piroctone which is an anti-bacterial active ingredient that soothes itching and irritations and finally glycerin which moisturizes the scalp to relax it from external aggressions.
Once the hair reaps the benefits of Kérastase Bain Divalent, we recommend using it with another shampoo that has proven effective on your hair type by alternating between the two and using the Kérastase one as a hair are treatment more than a regular daily rinsing shampoo in order to avoid your hair and scalp to accommodate to its effects and become immune to them.
“Kérastase Specifique Bain Divalent” is sold for $26.9/250ml. This price might seem on the high side considering that you can find L’Oréal treatment shampoo such as “Elvive Low Shampoo Total Repair 5” for only $6/400ml but is less expensive than a “Dessange Sublimateur – Séduction Brillance which retails for 38.6$/250ml. As mentioned above, the benefit of Kérastase is that it can be used as a treatment more than a daily rinsing shampoo once the benefits are reaped.
