PRP For Hair Restoration
What is PRP for hair restoration?
PRP is filled with seven growth factors and healing mechanisms. Growth factors are the messengers in the body, signaling cells to perform various functions. That’s why platelets are so important for wound healing, as they initiate new tissue growth. By putting the healing power of PRP to work on thinning hair, the growth factors help to “turn back on” hair follicles that have begun to spend more and more time resting.
The procedure is simple. After we take your blood, place it in a centrifuge to separate out the red and white blood cells, and concentrate the platelets and the growth factors, we then have PRP. Dr. Dahan simply injects the PRP back into your scalp at a shallow depth across the area you are experiencing thinning. From there, we let the PRP do its magic.
How does PRP restore hair growth to thinning areas?
What’s important for hair growth is the hair growth cycle. Human hair has three phases of the growth cycle: anagen (growth), catagen (transition), and telogen (resting/shedding). When we’re young, our hair follicles spend most of their time in the growth phase. But whether due to genetic predisposition (male or female pattern baldness) or simple aging, our hair follicles begin to spend more and more time in the resting phase. Some even become fully dormant. That leads to thinning hair because the follicles that have shed their hairs don’t quickly move back to the anagen phase to start growing new hair.
The goal of PRP is to get those resting follicles to kick back into gear and return to the growth phase and begin growing hair. When the PRP is injected in dozens of injections across the scalp in the area where the hair is thinning, the abundant growth factors stimulate resting follicles to return to action. As more and more follicles return to the growth phase, your hair first stops thinning, and then it begins to fill back in with new natural hair.
Who is a good candidate for PRP for hair restoration?
Both men and women who are experiencing hair loss are good candidates for PRP hair restoration with Dr. Dahan. However, the growth factors in the PRP work best when awakening follicles that only recently became dormant or are simply spending longer periods in resting phase. These hair follicles are still healthy and capable of growing hair. They could be headed to full dormancy, but they aren’t there yet. That’s why PRP for hair restoration works best when the patient notices early hair loss. Clinically, this is known as androgenic alopecia.
PRP isn’t effective for regrowing hair on areas of full baldness with long-dormant hair follicles.
How is the PRP injected into the scalp and is it painful?
Once your PRP is created, Dr. Dahan then injects it back into the scalp using a syringe with a very fine needle. The PRP is injected at approximately every half inch across the area of thinning hair. The injections are placed at a depth proven to stimulate the hair follicles. The injections are painless or have minimal discomfort since a topical numbing agent is applied prior to the PRP session.
How long will it take to start growing hair?
Most patients first notice decreased hair shedding. From there, real growth usually is noticeable after the first two to three PRP sessions. Dr. Dahan recommends that patients use vitamins or supplements that promote hair growth to achieve the best results.
How many PRP hair restoration sessions will I need?
Dr. Dahan recommends one PRP treatment every four to six weeks for three to six sessions, with follow-up treatments every three to six months, depending of the patient’s response to treatment. For most patients with thinning hair, this is viewed as an ongoing maintenance program to overcome the tendency for the hair follicles to become dormant.
Is there recovery after a PRP session? When can I wash my hair?
There isn’t really any recovery. You may take an over-the-counter pain medication if you feel any soreness, but you can shower and wash your hair immediately. Dr. Dahan usually recommends holding off one to two days with typical hair maintenance, such as blow drying, coloring, curling, etc.
Are there side effects with PRP treatments?
Because PRP is created using your blood, reactions are virtually unheard of. There is a very slight risk of bruising or infection, but this is a very safe procedure. We recommend that you discontinue any medications or supplements that may thin your blood at least eight to ten days prior to your treatment.
