Have you talked to your doctor to check for any kind of vitamin deficiencies or immune system problems? It could be a real issue, especially as a teenager. He/She will be able to help you with the transplant issues, but there could be even something more serious! Good luck!

If it annoys you, you should get some transplants. If it doesn’t annoy you, cut your hair short and have fun.

Try not using any heated tools on your hair. E.g straightners, curlers e.t.c.
If blow drying your hair…ALWAYS ALWAYS use a pre-treatment heat defence. I recommend Treseme, since it’s well-known and known to work a hell of good.
Try just using a shampoo, lots of bad conditioners tend to make hair weak and fall out.
Try not to use hairspray/gel too much. This can damage your hair at first, make it brittle, and obviously slightly harder to wash out. And not to colour your hair to much either.
I don’t think a hair transplant is an option at your age, I’ve heard a lot of the time it goes wrong and is totally noticable. Try clip in extensions or hair pieces . Glued ones, make the hair thinner.
Could be some vitamin deficiencies or something like that…I suggest just going to your GP for info.
I may sound like an idiot. But yes Im only fifteen, but my hair has also thinned out a bit over the past year or so. Just try different stuff, but ALWAYS remember to pre treat your hair!

I think you’ll be all right. And you can make the decision of getting hair transplants. I would suggest using V05 Extra Body Conditioner. And don’t brush your hair A LOT. That will cause breaking and some thinning. So just think positive thoughts, consult your doctor and take care of yourself!
