What is Rogaine?

Rogaine is used for hair loss to help regrow new thicker hair and prevent future hair loss in men and women. Hair growth may be seen as early as 2 to 4 months, when used regularly. Rogaine for women and Rogaine for Men are applied daily or twice daily depending on the product and person using it. They are available over the counter without a prescription.

Rogaine for Women is used to help regrow hair if you have gradually thinning hair or gradual hair loss on the top of the head, which may only become noticeable after years of gradual loss. It works best when it is used at the earlier stages of female pattern hair loss. Women's Rogaine foam is applied once daily to the affected scalp area, and the solution is applied twice daily.

Rogaine for Men is used to improve hair growth if you have inherited gradually thinning hair or gradual hair loss on the vertex at the top of the scalp. It is not intended for frontal baldness or a receding hairline. This medicine works best at the earlier stages of hair loss or thinning and is less effective when there is a larger area of hair loss. Rogaine for men is available as a foam and solution and is applied twice daily to the affected scalp area.

Rogaine will not cause permanent regrowth of scalp hair. You must continue using the product to keep the regrowth of your hair.

What is Rogaine used for?

Rogaine for women

Women’s Rogaine is FDA-approved to treat women 18 years and older with female-pattern hair loss, with gradual thinning hair or gradual hair loss on the top of the head, and a family history of this kind of hair loss.

Rogaine for men

Men’s Rogaine is FDA-approved for treating hereditary hair loss in men 18 years and older to help reverse the progression of hair loss on the scalp. Hereditary hair loss is when men experience gradually thinning hair or gradual hair loss on the top of the scalp in the vertex area, which has affected other men in their family. It is not intended for frontal baldness or a receding hairline.

Rogaine for beards and other hair loss issues

Rogaine for beards, eyebrows, and also for alopecia areata (AA), scarring alopecia, and hair shaft disorders has been used to improve hair growth; however, these uses are all off-label.

How long does it take for Rogaine to work?

Rogaine starts working in the first 2 to 4 months, with new soft, colorless hairs growing. From 4 to 6 months, new, thicker hair growth may become visible. To maintain hair regrowth, it is important to continue using minoxidil regularly. In the first 1 to 3 weeks of using minoxidil, you may have increased hair shedding.

How does Rogaine work?

Rogaine works by increasing the hair follicle's length of time in its growth (anagen) phase, which helps increase hair length and thickness. It also shortens the length of time in the shedding (telogen) phase, which means the follicles move more quickly into the growth phase.

Although the mechanism of action of this medicine for hair loss is not fully understood, it is thought to work by activating both extracellular signal-regulated kinase (ERK) and Akt and by preventing cell death by increasing the ratio of a protein called BCl-2/Bax.
