Im 43 years old my hair is falling, what's the best treatment?

See a dermatologist: Sometimes, medical problems like iron deficiency or hypothyroidism may be the cause. More commonly, female pattern hair loss is a slowly progressive problem. There are medicines that may help, notably finasteride and minoxidil. If medicines fail, hair transplantation is effective. You need to see a dermatologist for an evaluation of the problem and to start treatment

Full physicial exam: multiple causes: medical, metabolic, endocrine,stress, anxiety...my suggestion is a full exam and workup.

Probably diet: Commonest cause of falling hair is vitamin deficiency. I would suggest that you check out your diet and obtain a well-rounded multi vitamin.

Need cause 1st: There are many different causes of hair loss in men and women. Some of the more common are stress, hormonal, infection, other diseases like thyroid and lupus, and natural aging. The average human can lose 100 hairs a day and that's normal. Before we select a treatment, we should find the cause. Sometimes bloodwork and an examination can help find cause. See your doctor!
