Straighten Thin Hair

I feel this would make my hair look better and I would be able to keep them loose without being conscious of them all the time. Since I want to perform the chemical straightening at home, can you please recommend which product should I use? Would Wellastrate be a good option?
A: You can do a targeted service of almost any kind on the hair, as long as you carefully plan how you will keep the chemical isolated to the area you wish to use it on.
If, however, you mean "thinness" as in the texture of the hair being so fine that the hairs are less visible, I must caution you against at-home chemical procedures. I would strongly suggest you consult with a professional stylist who can physically examine and evaluate your hair, and advise you on (and assist you with) the problem you feel you have.
If your salon professional feels that your hair would respond to an at-home treatment safely, the Wellastrate product is a reasonable choice, just be sure that you select a formulation appropriate to your hair's needs. Even an at-home kit could be problematic if you choose a formula too strong for the texture of your hair.
