Platelet Rich Plasma for Hair Loss

Micro-Needling with Platelet-Rich Plasma Therapy for Hair Growth

What is Platelet-Rich Plasma (PRP) Therapy?
Platelet-Rich Plasma (PRP) Therapy is a ground-breaking therapy where your body’s platelets (found in plasma—a component of our blood) are used to stimulate hair follicles to regrow hair.  At least 8 essential growth factors are found in platelets. Platelet rich plasma, or PRP, is concentrated blood plasma that contains approximately five times the number of platelets found in normal circulating blood. Apart from red blood cells and white blood cells, our blood also contains cells known as platelets. The function of platelets is to promote healing and aid in the clotting of blood at the site of a wound. Platelets contain growth factors that promote regeneration of the cells in the body. PRP has been used in medicine for the last two decades. It has been proven to restore hair and is now used for hair loss.

Who can benefit from PRP Therapy?
PRP Therapy has been used for many years to help stimulate collagen formation in antiaging treatments. It has been proven to lessen acne scarring and stimulate growth of new tissue.  It is commonly used to help the body heal from athletic injuries. Recent scientific data has shown that PRP Therapy can also be an aid in treatment for patients who experience hair loss—it works equally well in men and women and treats all types of hair loss, including scarring alopecia. Patients with thinning eyebrows can also benefit from this procedure.

How is the procedure done?
A small amount of your blood is drawn, placed in a sterile tube, and spun in a centrifuge to separate the PRP. This process concentrates the platelet count to five times more than normal. A topical anesthetic cream is used to numb the scalp. The PRP is then extracted from the tube and dispersed onto the areas of concern using a micro-needling technique to introduce it to the scalp. Additionally, a series of direct PRP injections, using a fine needle, will complete the treatment.

How many PRP Therapy treatments will I need?
A series of 4 to 6 treatments, at 6 to 8 weeks intervals, is recommended for best results.

Is PRP Therapy Safe?
Yes. There is no risk of an allergic reaction or rejection since the PRP is derived is from your own blood.

How long is the treatment?
The entire procedure takes 45-60 minutes. You will need to come in 30 minutes prior to your appointment to sit with a topical anesthetic cream (included in the cost of the procedure).

Does PRP Therapy hurt and what will I look like after the treatment?
Patients will feel the pressure of injections and micro-needling during the procedure. A topical anesthetic cream is used to numb the area prior to your session to minimize any discomfort. Your scalp will look red immediately following your treatment; this redness will diminish in a few hours but may last up to 48 hours. Patients may also experience flaking of the skin 2-3 days post micro-needling.

How long does it take to see results?
The number of treatments required will depend on how you respond to the procedure and the extent of the problem being treated. The result is also dependent on whether micro-needling was used. Micro-needling creates micro “injuries” to the skin, significantly increasing our own natural healing mechanism, and improving outcomes over direct PRP injections alone.

How should I prepare for my PRP Therapy treatment with Dr. Davis?
In preparation for your treatment, Dr. Davis advises patients to discontinue oral blood thinning medications at least a week before treatment, unless prescribed by your physician. Avoid all pain relievers (Aspirin, ibuprofen, and even low dose baby Aspirin) except Tylenol (acetaminophen). Avoid Vitamin E, all multi-vitamins containing Vitamin E, cinnamon, horseradish, and herbal remedies such as fish oil, ginger root, gingko, etc. a week prior to treatment to prevent prolonged bruising.

Is there any special care that needs to be taken after a PRP Therapy treatment with Dr. Davis?
Patients are advised to leave the PRP solution on the scalp overnight. You can wash it off the following day with a gentle shampoo. It is important to avoid sun exposure and sweaty activities for at least 48 hours after your procedure.
