Hair Loss Product Review - Kerastase Specifique Intensive Scalp Treatment

Shapiro MD Hair Loss System

Kerastase Specifique Intensive Scalp Treatment is highly rated product on the market. Eager to know more about the treatment and how it works, we did some research.

In this article, we will provide with the information we managed to find on the product. In addition, we will go over some details concerning the science behind Kerastase Specifique Intensive Scalp Treatment.

Product and Treatment Explanation

The product is designed with all-natural ingredients that can help treat thinning hair and prevent hair loss. It is to be used for six to eight weeks. To get maximum results, you should apply one container of the product daily. If not daily, apply the product at least three times per week.

Product Ingredients

The formula for Kerastase Specifique Intensive Scalp Treatment is a blend of arginine, vitamin B8, vitamin PP, and citric acid.


Arginine is used by the body in the biosynthesis of proteins. Sources suggest that arginine can promote hair growth because the body also uses it as nitric oxide, which is widely believed to act as a vasodilator. How vasodilators work is by provoking relaxation of the arteries. When the arteries are relaxed, blood flow increases.

Therefore, using arginine may improve blood circulation within the scalp, thus stimulate the hair follicles.

In addition, since arginine is necessary to the biosynthesis of proteins, it can help enhance the production of keratin which is what the hair mainly consists of. Keratin keeps the hair strong, smooth, and shiny.

Vitamin B8

Vitamin B8, otherwise known as inositol, is another ingredient linked to hair growth. Despite this, there aren't many details on how the vitamin works to make the hair longer. However, research suggests that vitamin B8 can help repair hair damage.

Vitamin PP

Vitamin PP is another term for vitamin B3 or niacin. A supposed benefit of vitamin B3 for the hair is that counteracts the activity of dihydrotestosterone (DHT), the product of testosterone conversion. DHT is widely believed to contribute to balding. It can act as a vasodilator as well, improving blood circulation to the scalp.

Furthermore, the anti-inflammatory properties of vitamin B3 can fight off conditions such as seborrheic dermatitis, in which scaly patches appear on the scalp. Seborhheic dermatitis is a highly inflammatory condition and can result in symptoms like hair loss, dandruff, dry scalp, and itchiness.

Citric Acid

Citric acid is derived from mostly lemons and limes. It can aid in cleansing the scalp and preventing build-up in the hair follicles.

Science Behind the Product

Here are additional details on the science behind the ingredients in Kerastase Specifique Intensive Scalp Treatment.

Improving blood circulation within the scalp enables the hair follicles to receive more nutrients and oxygen. Not only does the hair require these components to grow but to stay healthy as well.

Vitamins can help prevent the effects of hair loss triggers such as DHT and free radicals on the follicles. Men that are bald are notorious for possessing high levels of DHT.

How the androgen and hair loss are linked is due to the the 5-alpha reductase enzyme, which is responsible for the conversion of testosterone into DHT. Research suggests that the enzyme is present in the hair follicles. DHT acts against the hair follicles through miniaturization, meaning the androgen shrinks them. As a result, the follicles produce hair that it is more prone to breakage.

More details would be necessary on how vitamins work to block DHT, but the provided information shows that there is a connection.

Furthermore, vitamins are known to act as antioxidants, meaning they can reduce oxidative stress brought on by free radicals. For instance, standing out in the sun for a prolonged period of time can cause damage to the hair follicles. Other risk factors for damaged hair follicles include air pollution, chemical treatments, certain foods, etc.
