While these supplements support hair health, persistent hair thinning, visible scalp, dandruff, and acne often stem from underlying hormonal or inflammatory factors that require targeted medical treatment. Three to four months is a reasonable trial period, and since you haven't seen progress, it is best to consult a dermatologist. They can properly diagnose the root cause and prescribe specific treatments?such as medicated anti-dandruff shampoos, topical solutions, or targeted acne therapies?tailored to your needs. Please stay positive; with the right medical guidance, these concerns can be successfully managed.

Among the treatments you mentioned, finasteride is medically the most effective as it directly targets the hormonal root cause of male pattern hair loss. Follihair, Hairful, and Keraglo Men are nutritional supplements; while they support overall hair strength, they cannot stop genetic hair loss alone. Regarding biotin shampoos, they can improve hair texture and thickness, but because they are washed off quickly, they don't significantly stimulate new growth. For the best results, I highly recommend consulting a dermatologist.

New Follihair contains vitamins and minerals, including iron, which can commonly cause dark stools during use. However, developing severe black diarrhea five days after finishing the course is unlikely to be a delayed side effect of the supplement. Because black, loose stools can sometimes indicate other digestive tract issues or infections, it is important to have this evaluated. Please stay well-hydrated and consult a healthcare professional soon for a proper check-up so they can help you find relief.

Shedding lasting over seven months is often due to telogen effluvium (triggered by stress, hormonal shifts, or a past illness) or early female pattern hair loss. To find the exact cause, I recommend consulting a dermatologist. They can evaluate your scalp and order blood tests to check your thyroid, iron (ferritin) levels, and hormones. Once diagnosed, highly effective medical options like topical minoxidil can be considered.

It is very common to experience shedding after discontinuing minoxidil, as the hair follicles miss the stimulation it provided. While natural options like onion juice and fenugreek paste have mild anti-inflammatory properties, they lack the scientific evidence to effectively promote regrowth or prevent the shedding that occurs after stopping minoxidil. I assure you that you have options. I highly recommend discussing your concerns with a dermatologist who can help you find a safe, sustainable plan that fits your lifestyle.
