Hair loss on both temples is an early sign of hormone-related male pattern baldness. This condition occurs when the hair growth cycle is disrupted, leading to more hair shedding than new growth. Alternatively, hair follicles may gradually shrink under the influence of hormones, eventually being replaced by scar tissue. Over time, hair on the temples thins, forming characteristic baldness patterns. This condition affects men more than women, and its severity increases with age.

According to the American Hair Loss Association, over 95% of hair loss cases in men are related to male pattern baldness. Of these, about two-thirds of men experience significant hair loss before age 35, and nearly 85% have noticeably thinning hair by age 50. Common patterns of male baldness include frontal baldness (M-shaped), crown baldness (U-shaped), and patchy baldness (O-shaped).

Male pattern baldness is closely linked to the male hormone testosterone. An imbalance between testosterone and dihydrotestosterone (DHT)—a hormone converted from testosterone—causes hair follicles to shrink. This prevents hair germ cells from receiving essential nutrients. Hair becomes weak, thin, brittle, and struggles to regrow, eventually leading to male pattern baldness.

Other factors can also weaken hair germ cells and cause hair loss and male pattern baldness, including: genetics, prolonged stress, scalp conditions, nutrient deficiencies, nutritional imbalances, or overuse of styling chemicals.

If hair loss is abnormal and persists for several weeks, leading to a noticeable reduction in hair volume or increasingly visible scalp on the temples, you should consult a Dermatology specialist to identify the cause. Early detection and intervention help preserve hair follicles, increase treatment effectiveness, and limit the risk of baldness.

In addition to doctor-prescribed treatment, men should maintain a balanced diet, get sufficient sleep, manage stress, rest adequately, and care for their scalp properly.

You can consider long-term supplementation with specific essences for men's hair, such as: eurycoma longifolia, saw palmetto, aged black garlic, american ginseng, cynatine. These ingredients help protect hair germ cells, nourish hair follicles, support reduced shedding, slow down baldness, and promote strong, healthy hair growth.
