A dermatologist, as you may already know, is a doctor who treats conditions of the skin. However, this type of professional does much more than just clear up acne or treat skin cancer, and you may want to visit such a professional for a variety of reasons related to your health and appearance.
A dermatologist often treats conditions related to hair loss and bald spots, thinning hair, brittle hair and other such conditions. This is because your hair is attached to your skin. If you have dry skin on your scalp, clogged pores that don't allow hair follicles to grow, damaged skin such as from harsh shampoos or sun exposure, then you will probably see the result of these skin concerns in the appearance of your hair. A dermatologist can note if you need a medicated shampoo or some other type of treatment that will address the skin problems on your scalp so that your hair can grow healthy and thick.
As with your hair, your nails are connected to your skin. You may not think of skin problems as being the reason for brittle and damaged nails or nails that simply refuse to grow, but if your skin is healthy and strong, it will provide the nourishment your nails need to also grow healthy and strong. A dermatologist may also be able to examine your nails and pinpoint other health concerns you might have, such as lack of iron or the B vitamins, low blood pressure or poor blood circulation, dehydration and the like.
If you've had any type of invasive surgery, and especially any surgery related to the skin itself, you may now have very deep and unsightly scars. Don't assume that you're simply stuck with those scars for life as a dermatologist can help determine how to lessen their appearance, cover them over or treat them so that they gradually fade over the years.
Options like pulsated light or laser therapy, or a micro-dermabrasion procedure, can often stimulate collagen growth so that new, healthy skin grows under the area of the scar, improving your appearance. A dermatologist can also tell you how to protect that area of the skin so that it doesn't get more unsightly due to sun damage, chemical exposure, dryness and other such irritants.
Visit a skin clinic and dermatologist if you have any pressing concerns related to the health of your skin.
