Boy Teenager long hair style ?

When I was little child like about 13 years old I had really thin hair but after that my hair is becoming thicker, I'm sixteen now and i want to have my hair as it was before. Is this just a teenager fase ? what products do you recommend to make it thinner, i mean shampoo,vitamin ....thse kind of stuff,,,

I got a lot of hair everyone says that it is a undefined colour like brown and blonde at the same time.. lol what can i do ?

Okay, your color is not undefined, it's sandy blonde or light brown (however you want to look at it). Also, why on Earth would you ever want thin hair?!!! When you're older and (heaven forbid) you start going bald, you'll wish you had thick hair like you did then you were a teen. Until then you could grow it to shoulder length and then get your stylist to layer it. Maybe with thin, shaggy bangs? It will feel thinner and lighter.

There are NO products to make your hair thinner. You are becoming a man and when you reach tne mid 30s you are going to wish that your hair NEVER thins out so just go to a salon and get a nice haircut.
