Thinning hair, widened parting, or bald spots can have various causes. One cosmetic product alone does not explain them.
Where to start?
First, find out the cause with a dermatologist. Do not choose procedures solely based on promises to regrow hair.
When to see a specialist?
If you notice thinning or bald spots, it’s worth consulting a dermatologist without delay.
