What's causing the gradual thinning of my hair for the last 7-8 years? What can be done? (photos)

For hair regrowth, I suggest the following to my patients:
Start Theradome now (see link) and in office PRP/acell, you can do early transplant if you want. You need a formal evaluation to see what type of hair loss you may have. when you have hair loss its best to do a full hormonal workup for internal optimization plus scalp biopsies or scrapings to rule out any stress related, inflammatory, autoimmune or infectious causes of hair loss. In general most people with early hair loss have telogen (stress related) and/or androgenetic (normal aging) and both can be treated with in office treatments like steroid injections, PRP/acell, Exosomes and at home treatments like oral medications, oral vitamins like Viviscal, topical exfoliating sprays like Restorsea, and weekly growth factors like anteagemd. See an expert for an evaluation. If hair loss is significant it may requires hair transplant (follicular unit translation) Best, Dr. Emer

Based on the information provided, it is uncertain whether the cause of your hair loss is male pattern baldness, chronic TE, or something else.You should consult a qualified hair loss physician, who will examine your scalp and establish a diagnosis.

There are many reasons for thinning of the hair. There are also many treatments ranging from topical medications, to PRP treatments, to hair transplant. The best place to begin is by visiting with a hair loss expert for an evaluation.

Hello Dear, you should definitely go to a dermatologist consultation, or hair specialist. There are different types of Alopecia, and probably you're going through different at the same time, you should have some blood test done, do a tricoscopy of your hair and other things. Don't let time pass by. Do something about it sooner, rather than later. 

Secure an appt with a Dermatologist that specializes in hair loss so they can do the proper blood work and evaluation that needs to be done.

Best of luck!
