Hi, this is my first post. I'm 30 and my hair has been thinning around my part and in the back for about 5 years (basically all over, but that's where it's noticeable). I've started going to my dermatologist, she recommended iron after some tests, and I've been on rogaine for about 2 years... My question has to do with extensions. Do you think they will cause any damage? My stylist says no, but I am still wary. I wanted synthetic but she recommended real hair based on my hair type, etc. (for the same price, about $350-$400). She said she would do 60 to give the back some more fullness, and maybe some underneath my bangs. I'm wondering if I should start with about 30 instead of 60 for my first time. I'm concerned about the gluing, whether it will cause further damage. And also the discomfort, and whether I'll be able to wear my hair in a ponytail. She said they last 4-6 months, but based on what I've read, I will probably have them taken out after 2 months. Also, I wonder if the rogaine will damage the glue, something I need to ask her about, but I did see another post here that said something to that effect. I'm not sure if my stylist has worked with a lot of people with thinning hair, but I just moved here to chicago, so I have yet to find someone who has. Any advice you have would be great, this is a very helpful site. Thanks!
