by Causes of Hair Loss
There are various reasons why someone may experience hair loss or thinning hair. Some of the most common causes include:
Genetics – If hair loss runs in the family, someone is more likely to experience it as well. Male pattern baldness, also known as androgenetic alopecia, is the most common cause of hair loss in men and women. It is hereditary.
Stress – High levels of stress can cause hair shedding and hair thinning. Stress triggers hormones in the body that signal hair follicles to prematurely enter the resting phase.
Certain medical conditions – Alopecia areata, an autoimmune disorder, can cause patchy hair loss. Other infections, thyroid disorders, nutritional deficiencies may also cause Hair Loss Treatment.
Medications – Some cancer drugs, blood thinners, and antidepressants can cause hair loss as a side effect by interfering with hair growth cycles. If hair loss only starts after starting a new medication, talking to a doctor can determine if a medication change may help.
Hairstyles – Tight hairstyles that cause prolonged traction on hair follicles like ponytails, braids and buns worn for many hours every day may cause traction alopecia. This puts tension on hair roots and damages follicles over time.
Pollution and environment – Air pollution and environmental toxins damages hair follicles and causes oxidative stress that accelerates hair shedding.
Non-Surgical Hair Loss Treatments
There are several FDA-approved non-surgical options to treat hair loss and stimulate hair regrowth. These include:
Minoxidil – Minoxidil, sold under the brand name Rogaine, is a topical solution or foam that is FDA-approved to treat genetic hair loss on the scalp. It comes in 2% and 5% strengths to be applied directly to the balding areas once or twice daily. Minoxidil dilates blood vessels in the scalp to deliver more nourishment to hair follicles and stimulates regrowth in most men. Women have shown to respond positively as well. Results may be seen within a few months, with maximum benefits seen in 6-9 months. Hair growth ceases if it is discontinued.
Low-level laser therapy (LLLT) – A handheld laser comb, when used for about 15 minutes 2-3 times a week, is thought to stimulate cell metabolism in hair follicles and promote hair growth. Research has shown its efficacy comparable to 2% minoxidil. It is considered safe with very minor side effects like skin discomfort rarely. Results may be seen in 4 months but treatment must be consistent.
Prescription medications – FDA-approved oral medications like finasteride (Propecia) block conversion of testosterone to dihydrotestosterone (DHT) that contributes to male pattern hair loss. Dutasteride (Avodart) similarly works by blocking both types (I and II) of 5-alpha reductase enzymes. They prevent further hair loss and stimulate regrowth of fine, short hair in many patients. However, they may cause sexual side effects like lowered libido in some. Recent research suggests they are also safe and efficacious for females with hair loss. Spironolactone taken by women blocks DHT as well to reduce hair shedding.
PR P (Platelet-rich plasma) therapy – One’s own blood is drawn, enriched with platelets, and injected into balding areas. Platelet-rich plasma contains growth factors that promote natural wound healing and new cell growth. Some research indicates it may boost hair regrowth results when combined with minoxidil. A small number of treatments are required, usually at 4-6 week intervals initially. Side effects are mild bruising or swelling at injection sites.
Nutritional supplements – Vitamins like biotin, vitamin D, iron, and essential minerals support existing hair and prevent hair loss if a deficiency exists. While some supplements have studies showing benefits, they are rarely as impactful as FDA-approved treatments when used alone.
Surgical Hair Restoration Options
For those with significant hair loss not adequately addressed by the above remedies, surgical hair restoration may be an option to consider:
Hair transplants – This procedure involves surgically removing hair follicles from the back/sides of the scalp and replanting them within balding areas. Both follicular unit strip surgery (FUSS) and follicular unit extraction (FUE) are commonly used techniques today. Transplanted hair grows permanently just like the hair from which it was removed. Multiple procedures are sometimes required to achieve satisfactory density. Donor scar or shock loss can occur but is uncommon.
Scalp reduction – During this procedure, bald areas of the scalp are surgically removed or reduced in size, shrinking the bald area and bringing existing hair closer together to appear denser. As with any surgery, risks exist including scarring, infection, and irregular appearance if not performed skillfully by an experienced board-certified dermatologic surgeon.
Choosing the Best Hair Loss Treatment
While hereditary hair loss cannot be prevented, addressing other risk factors and using effective treatments can help restore or maintain a full head of hair. Different options exist, and consulting an experienced dermatologist rather than relying solely online can help determine the best individualized plan to match hair loss severity and personal treatment goals. With diligence and consistency, hair loss sufferers have many promising options for effective hair regrowth available today.
