Hair mesotherapy is also known as mesoplasty or mesohair. It involves injecting medications directly into the scalp. This technique acts on the epidermis, dermal connective tissue, circulation, and the immune and neurosensory systems.

It can help in improving certain forms of alopecia like telogen effluvium, androgenetic alopecia, alopecia areata, and stress alopecia. However, there is very little scientific evidence to show that this technique can eliminate hair loss.

The objective of this treatment is to restore and increase microcirculation in the scalp, provide nutrients, slow down the shrinking of follicles, and stimulate hair growth. It claims that the following chemicals and ingredients can stimulate hair growth and encourage new hair production.
