The Difference Between Dragging Through Your Day And Feeling Great On Your Feet? These Arch Support Insoles

1. Expect Initial Hair Shedding

The idea of losing hair while trying to grow it may sound alarming, but Dr. Adel explains that this shedding is temporary.

“The initial shedding that happens with minoxidil only lasts around two months while your hair cycle adjusts,” she says. “If you can push through that, the results on the other side are absolutely going to be better.”

This phase is normal and signals that the treatment is activating new hair growth.

2. Commit for the Long Haul

Minoxidil isn’t a short-term fix. To maintain the hair you grow, you need to stick with it consistently.

“If you want to keep all of that hair you’ve worked hard to grow, you need to continue using minoxidil long-term,” Dr. Adel says. She compares it to maintaining a six-pack: stop your routine, and the results fade.

3. Opt for the 5% Men’s Version

Contrary to the label, women can safely use the 5% men’s minoxidil instead of the 2% formula. “Not only is it cheaper, but it also gives the best results,” Dr. Adel explains. “Ignore the packaging warning—it’s fine for women to use.”

4. Keep It Away from Pets

Pet owners, take note: minoxidil is toxic to animals. Dr. Adel stresses keeping the solution well out of reach from cats and dogs to prevent accidental exposure.

5. Pair for Maximum Results

To get the fullest, thickest hair possible, Dr. Adel recommends combining minoxidil with other tools or treatments.

“Use a dermaroller, tretinoin, or an LED light mask alongside minoxidil,” she says. “This combination will give you the absolute best results.”

The Bottom Line

For women over 40, minoxidil can be a highly effective solution for hairline thinning—if approached correctly. From understanding the initial shedding phase to committing long-term and using the right formula, Dr. Adel’s tips make it easier to see real, lasting growth. Paired with additional treatments, this routine can help you achieve the thick, healthy hair you’ve been hoping for.
