I mean…if it’s shedding efect it’s not so bad…but..i don’t know. could you help me? Doctors in Spain don’t take it serious…
Thank you!

You may be going through a very active phase of hair loss, genetically inspired. You need to consult with your doctor. If I was your doctor, I would have had your scalp mapped out for miniaturization so as you follow the progression of hair loss, there would be insights into the changes that may point to the cause.
