Hair Growth

The hair growth test evaluates the effectiveness of a product in promoting hair growth. This can be done through various methods, including measuring the length and density of hair or the anagen/telogen ratio. The anagen/telogen ratio is the ratio of active growing hair follicles to resting or shedding hair follicles. A higher ratio indicates greater hair growth.

To conduct this test, a group of participants is selected, and their hair growth is monitored over a specific period. The participants may be divided into a control group, which does not receive the product, and a treatment group, which uses the product regularly. The hair length and density or the anagen/telogen ratio of both groups are compared to determine the effectiveness of the product in promoting hair growth.

Hair growth can also be evaluated through scalp imaging or trichoscopy, which involves the use of a special microscope to examine the hair follicles. This allows for a more detailed analysis of hair growth patterns and can provide additional information on the effectiveness of the product in promoting hair growth. This information could be highly beneficial for companies that produce hair care products to support their claims and enhance the satisfaction of their customers.
