Women’s hair loss treatments compared: oral vs topical minoxidil, spironolactone, PRP, and low-level laser—who’s a candidate and what results to expect
common.months_ago
Hair thinning is common, especially in women, and can have a major psychological impact. Many options can slow shedding and promote regrowth: over‑the‑counter topical minoxidil (Rogaine), oral nutritional supplements, prescription spironolactone to reduce hormone effects (and often improve acne), oral minoxidil, platelet‑rich plasma (PRP) injections that deliver growth factors to the scalp, and low‑level red‑light therapy. A dermatologist can tailor a plan and combine treatments for better results.
Dermatologist: A medical doctor who specializes in conditions of the skin, hair, and nails, including hair loss.
Hair thinning: A reduction in hair density that can make the scalp more visible; a common form of hair loss in women.
Minoxidil (topical): An over‑the‑counter scalp treatment that helps stimulate hair growth and slow shedding; brand name Rogaine.
Rogaine: A brand name for topical minoxidil used to promote hair growth.
Oral nutritional substances: Vitamins or supplements taken by mouth that may support hair growth when recommended by a clinician.
Spironolactone: A prescription pill that reduces the effect of hormones on hair follicles, helping hair regrow; can also improve acne.
Hormones: Body chemicals (like androgens) that can shrink hair follicles; blocking their effects can help with female hair thinning.
Acne: A skin condition of clogged pores and inflammation; spironolactone can often help improve it.
Minoxidil (oral): A low‑dose pill form of minoxidil that can promote hair growth under medical supervision.
Platelet‑rich plasma (PRP): A treatment using a patient’s own blood components rich in growth factors, injected into the scalp to stimulate hair growth.
Growth factors: Natural proteins from platelets that signal cells to repair and grow; used in PRP to encourage hair growth.
Low‑level light (red light): A light therapy that can stimulate hair follicles and is often combined with PRP or other treatments.
