Time for "The morning stir." A breakthrough new treatment for thinning hair. The haanswer may already be in your body. Linzie Janis has the details. Why is my hair falling out. Reporter: The answer may no longer mean this. I'm not only the president, I'm a client. Reporter: A promising new hair loss treatment for women and men without surgery, drugs, expensive ointments. Look at these before and afters. And the secret may be something you already have. This is the best kept secret in the world. Reporter: It's called platelet rich plasma therapy. Prp. It works by injecting the platelets from the patient's own blood directly into the scalp, saying they contain growth factors that stimulate the regrowth and thickening of hair follicles. Tanisha believes years of pulling her hair back caused her to lose some around her face. I had to make sure my hair was in front, never pushed back. Reporter: She says just weeks after her first treatment, the hair started to regrow. This after just one treatment. It's amazing. You can see where the hairs have grown. Reporter: Is this a cure for baldness? It's not a cure. It's a treatment. What we're doing is increasing the diameter of the size of the hair follicle and keeping the hairs that would stop growing in the grows phase. Reporter: Blood is drawn. The plasma separated. Giving hope to millions with thinning hair. For "Good morning America," Linzie Janis, ABC news, new York. And Dr. Jennifer Ashton is back. What is your take? Is there downside? Incredibly promising. I've seen the results. They're impressive. There's a little discomfort with the small needle prohibitiicks. There's the cost. About $400 or so per treatment. It sounds like a lot. You balance that against what people with thinning hair spend to treat that problem, it's probably a wash. You said per treatment. About how many do you need? You can see results after one. Typically, it's one, another one a month later, and probably a third. It varies from person to person. I don't have to tell you. It's very emotional for men and women when they start to lose their hair for various reasons. There are various causes for why you lose your hair. Absolutely. There are hormonal reasons. Side effects of many medications that we tend to not think about until we see the hair thinning. And age. But this is so promising. It works in all ethnic types. This is potentially a big advance. What can you do if you're losing hair? I say start with a visit to a dermatologist. They may do a scalp biopsy. Multivitamins. B complex. Biotin. Rest your hair. Don't style it, don't wash it. Give it a break. And the over-the-counter products, they do work. I caution people, male or female, if you use them, put a towel over your pillow because you'll grow hair on your face as well as your head. Who knew? There you go. Thank you, Jen. Over to Lara.
