Does Hair Thickening Shampoo Work? Detailed Answer

Yes, hair thickening shampoos do work. However, the results are not permanent. We all are born with a particular number of hair follicles.

Each follicle has a single hair root, meaning only one can grow from a single hair follicle.

Apart from panthenol, hair-thickening shampoos also have amino acids, botanical extracts, and vitamins, increasing hair’s shine, elasticity, and moisture.
