Hair stimulation by injection involves minimally invasive techniques which are commonly used in the medical and aesthetic fields, some of them since the 1950s. These techniques are now part of the therapeutic tool kit to slow down the progression of alopecia or to stimulate hair growth, whether it involves mesografts, PRP treatment, mesotherapy or microneedling. They are sometimes recommended as a complement to a hair transplant or medication.

Microneedling

What is hair stimulation by injection?

Hair stimulation by injection involves injecting substances into the scalp which will improve the vascularization of the scalp, stimulate cellular activity of the hair follicles or normalize hair loss, depending on the case.

For which patients?

Hair stimulation by injection is recommended in cases of telogen effluvium, androgenetic alopecia or even alopecia. It can be done on both men and women.

What are the results?

Several studies have shown that hair stimulation techniques by injection can normalize hair loss, revascularize the scalp and even revive the hair follicles in some patients. Some techniques are used in addition to hair transplants or medication.

The different techniques of hair stimulation

Mesograft

This is the most recent hair stimulation technique. Stem cells from the scalp are used to regenerate deficient hair follicles. Studies have shown that mesografting can increase hair thickness in patients with androgenic alopecia. A mesograft session and annual maintenance sessions will result in visible and lasting effects in most cases. It is often recommended before a hair transplant.

PRP Treatment

PRP treatment is a non-invasive method that has been used for over 20 years to fight hair loss. The treatment involves the use of platelet-rich plasma (PRP) to activate microcirculation and regenerate the cells of the hair follicle. Hair loss decreases significantly after the first treatment session and the hair density can increase. It can also be used as a complement to a hair transplant.

Hair Mesotherapy

Hair mesotherapy involves injecting a combination of polyvitamins into the scalp. These polyvitamins stimulate blood circulation in the scalp, while nourishing the hair bulbs. After two months of treatment, hair loss is slowed down and hair diameter increases in some patients.

Microneedling

Microneedling is a technique that stimulates the scalp’s tissues. Microperforations are made by the doctor in the epidermis of the scalp to trigger a healing process that improves blood circulation and promotes the production of elastin and collagen. It takes two to four sessions to normalize hair loss and in some cases stimulate hair growth.
