Our series the new beauty boom. Over a56 million Americans suffer from some form of hair loss and approximately 40% are women. It's a problem that affects confidence and self-esteem. But now a new treatment may hold promise in helping men and women regrow their own hair. ABC's Mara schiavocampo has the details. Reporter: Move over hair club for men. I'm not only the hair club president but I'm also a client. Reporter: Now a promising new hair loss treatment for women and men that may help to regrow and thicken hair without surgery, drugs or expensive ointments. Just look at these went numb. I'm extremely worried. Reporter: A few days later Kim was able to learn her up in ppanco dgcetiou R but from her home in Atlanta. Doct ors not clearing her to fly crosntry to L.A. In time for the show. And then a bombshell in the ballroom. In the instance of illness or other health-related matters affect participant's in the game they, must withdraw. ? Reporter: Kim's fans rallying, ait petion reaching more than 22,000 signatures. To bring back Kim and partner Tony dovo Kim zolciak. Thank you for having me. This plane trip to the show was the first plane stroke. How are you feeling? I'm feeling great. I was very nervous, obviously, on the had fine hair and I've always wanted fuller volume. Reporter: She says weeks after her first treatment she noticed a difference and here she is after five treatments. I feel the hair coming in. I feel the thickness. I love the results. Reporter: At just 22 years old Joseph's hair started thinning. He tried every over-the-counter product available. Over time it just got worse and worse. I didn't know what else to do. Reporter: He's had five procedures now and gained more than just a head of hair. It gave me my confidence back. It helped me to, you know, helped me to want to go out again. I don't have to we are a hat and definitely boosted my confidence. Reporter: Some studies suggest that while the results look good, they may not be long lasting. Still, the procedure is giving hope to millions with thinning hair. For "Good morning America," Mara schiavocampo, ABC news, new Jersey. Let's talk to Dr. Jen Ashton about this. Those are pretty remarkable. What do you say to people dealing with this. This is incredibly upsetting so we need to be empathetic. Be patient and let me show you why. It has to do with the science between the life cycle of a hair follicle. Think of three stages, first one is anogen, the active phase. 90% of our hair is it in this phase. It lasts for two to six years. Next phase is the catagen, transition, lasts a couple of weeks, a minority of your hair follicles are in this and final phase is telogen, resting face and if you start a therapy today you might not see results for a couple of months so you do have to be patient. What does it mean to this prp is not fda approved? Well for those of us in clinical medicine it doesn't mean that much. We use things awe the time that aren't fda approved. That means they need more study and a good informed concept process understanding the risks versus benefits but the science behind how prp is thought to work is pretty cool. Let me show you. If you see regular thinning hair, you inject these growth factors directly into the scalp. It does several things it increases the diameter or density of the existing hair follicle, recruits new growth and it's thought to even prevent the existing hair from falling out. I actually had this done. You're going to see my before and after pictures. I had had about hairs on my head on the left. After four treatments I had a really significant result. But, again, it's not for everyone so it's not going to work for patients who have scarring on their scalp. It's great for male pattern baldness or traction alopecia for people with extensions in and actively studied. If this doesn't work what does work? A lot of things you can do and take. In terps of things you can take, minoxidil over the counter works. The prescription drug Fe fenasteride and the vitamin B buy continue can help too and what you can do rest your hair. Don't overprocess, don't overcolor. If there's a medical cause, treat that underlying medical cause. That's key but this is exciting research. It is and I bet you'll get a lot of questions throughout the morning. You will be on Twitter @drjashton.
