Goodluck! And that is good advice to go see a dermatologist or something if you really believe it is thinning, or get a checkup. I don't know if you are on any medication, but some of those can interact too.

But it also just can depend on what the growth cycle is, and how much you detangled it before (if it's getting matted it's probably causing more to be tangled) and how often etc. I can't go more than a couple of days without detangling my hair. Detangle gently with lots of conditioner on it.

And of course it will look thicker when it's curly. And don't put the clips in too tight!!

Biotin is great for growing your hair and making it stronger (and your nails). I found out about it on this very board. And I think it's better than all those expensive hair vitamin combos.

Sorry about your thumb!
