Minoxidil was a drug first used to treat blood pressure and based on side effects, later used to treat hair loss. Minoxidil is a topical application used directly on the scalp, and can be used by men and women. It is most popularly sold under the brands Rogaine and Regaine in 2% concentrations for both men and women, and 5% for men. Minoxidil works by extending the hair growth cycle, and delaying the hair shedding cycle, so more hair is present on the head at a given time. How the drug achieves this is not exactly known, but it is believed to be linked to its blood circulation properties. Minoxidil does not stop or delay hair thinning, nor does it make hair thicker.
Minoxidil, which is most often used as a topical application, doesn’t thicken thinning hair. Minoxidil appears to work by delaying the natural hair shedding cycle, and prolonging the growth cycle so there is more hair on the scalp, so hair appears fuller. When minoxidil works, it does take time for results to be noticeable. However, if minoxidil use is stopped, or if its effectiveness wanes over time, hair delayed from shedding can suddenly shed all at once. Losing gains from minoxidil with time makes it a wasteful, and unsustainable treatment for female pattern hair loss.

Finasteride, often under the brand name Propecia, is an inhibitor of the enzyme 5-alpha reductase. Finasteride is an oral pill taken daily, in a 1 mg concentration for hair loss. A 5mg concentration of finasteride is used to treat enlarged prostates. 5-alpha reductase converts the hormone testosterone to dihydrotestosterone (DHT), which affects men with DHT-sensitive hair follicles. Hair follicles affected by DHT grow progressively thinner with each hair growth cycle, and eventually disappear if left untreated. By blocking the conversion of testosterone to DHT, finasteride can slow hair thinning, and in some cases have a slight effect on thickening thinning hair in men. Depending on the study, finasteride is beneficial in about 50% to almost 60% of men taking the drug. Finasteride is FDA-approved for men, and Dr. Prasad only prescribes it for male patients. Some doctors prescribe finasteride to women, but even with elevated DHT-levels, women do not have a significant level of DHT in their systems.

DHT-sensitivity is a major factor in male pattern hair loss, and is medically known as androgenetic alopecia, or androgenic alopecia. About 95% of all hair loss cases are cases of androgenetic alopecia. DHT disrupts the normal hair growth cycle from the roots of the hair follicles (dermal papillae) in men with scalp DHT-sensitivity. Hair follicles have androgen (hormone) receptors. Level of DHT-sensitivity varies in men. Men with earlier onset of pattern hair loss such as in their 20s or 30s, and rapid hair thinning have a higher level of DHT-sensitivity. Men who start hair thinning later such as in their 40s and older are less DHT-sensitive, and have a slower rate of hair thinning.
As an effective DHT-blocker, finasteride’s primary role in male pattern hair loss treatment is slowing hair thinning and hair loss progression. Although some men report increased hair thickness with finasteride alone, thickening effects tend to be limited. For most men, expectations for finasteride should be slowing, and stabilizing hair thinning.
TrichoStem® Hair Regeneration is not a DHT-blocker, so it is not a replacement or alternative to finasteride. That being said, patients on finasteride for years have increased their hair growth, and hair thickness after the TrichoStem® Hair Regeneration treatment, so while DHT-sensitivity is a major factor in male pattern hair loss, it is not the only factor. Finasteride is part of the treatment plan for male TrichoStem® Hair Regeneration patients, especially for younger men with high DHT-sensitivity. Younger men who refuse to take finasteride after the TrichoStem® Hair Regeneration treatment may not have the most optimal results, and results may last shorter than 3-5 years expected from female, and older male patients. While finasteride is still prescribed to older male TrichoStem® Hair Regeneration patients for best results, older men with less
DHT-sensitivity have seen increased hair thickness and growth without taking finasteride, with results lasting 3-5 years, or longer.
Sexual side effects associated with finasteride are very rare, occurring in less than 2% of men in initial studies. The benefits of finasteride for men with pattern hair loss do outweigh the risk. If risks are experienced, finasteride use should be stopped, and consultation with the prescribing doctor is needed. In Dr. Prasad’s experience prescribing finasteride since the early 1990s, he has not seen any of his patients suffer from long-term side effects of finasteride, and the few that did experience side effects were able to fully recover. It’s important to keep in mind that there other common causes of erectile dysfunction among men who have never taken finasteride, which include: aging, stress, lack of exercise, smoking, excessive
alcohol use, and other factors that affect health, and sexual health.
TrichoStem® Hair Regeneration can replace other hair loss treatments like minoxidil, PRP, and even hair transplant surgery. While it cannot replace finasteride completely in young men, it can thicken thinning hair, and stimulate healthier hair growth more than finasteride alone.
