L’Oreal is one of the biggest names in hair and skin care. Based in Paris, this huge conglomerate is always conducting research to improve their products. Keratase is the brand name for their foray into the hair loss prevention market. Whenever a big player like L’Oreal puts a product on the line, everyone stands up and pays attention, because their customer satisfaction rage is high along with their sales.

Keratase Lotion Densitive GL is similar to other products that cool the scalp, bringing blood to the surface. The addition of vitamins and minerals is designed to nourish the scalp and hair follicles.


Vitamin PP

I’m not sure what the PP stands for. Obviously the vitamins are intended to help nourish the scalp and fight any scalp conditions present. As I’ve mentioned about other products, I’m not really impressed when vitamins are added as part of a topical ingredient, simply because absorption takes place primarily in the digestive tract.

Mineral Molecules

Minerals are important for nutrition. L’Oreal added minerals to Lotion Densitive for the same reason they add vitamins—for hair and scalp nutrition. I’m not sure if molecules mean they have engineered something different with their added minerals or not. It could just be power words meant to impress customers.

Cooling Agent

Many different ingredients cause a cooling effect on the skin. They can feel cool and refreshing. Many topical pain relievers have a similar effect. Your skin may turn red for a short time after using this product because it brings blood to the surface of the skin.

How it Works

These ingredients together are designed to provide intense nourishment and help maintain healthy blood flow to the scalp. By doing these things, the company believes that DHT is cleansed away and hair follicle health is improved.


It costs $40 for a 125ml bottle of Keratase Lotion Densitive GL. That is certainly not cheap. The price is supposed to matter less because they say it doesn’t take very much lotion to get the intended job done for your hair.


I would not recommend this product or any other Keratase preventive products. L’Oreal is a respected company that has always been at the forefront of hair and skin care revolutions. If you want to try it, go ahead because it won’t harm you. Remember that no product works overnight, so you will need to use it continually for at least 3 months to see any possible results. I personally don’t think it will do anything.
