You may have first noticed it in the shower.

Then your part started looking a little wider. Your ponytail didn't feel quite as full. Maybe the hair around your crown or hairline wasn't looking the way it used to.

At first, it's easy to tell yourself it's temporary.

You change your shampoo. Try a supplement. Add another serum. Maybe you simply hope it'll sort itself out.

But when the changes continue, one thing becomes clear:

Your hair needs more than another product you use for a few weeks.

Hair thinning can have different contributing factors, and understanding what's happening is the first step toward choosing a more targeted routine.
