But if the new hair looks like it’s a different color than the hair you had before, it’s reasonable to be a little concerned about what that means.
So we spoke to world-renowned hair loss expert and Keeps medical advisor Dr. Antonella Tosti about what hair color changes mean and whether or not you should be worried about them.
“Hair affected by male pattern baldness becomes thinner, shorter, and lighter,” Dr. Tosti says. “Hair loss treatments like minoxidil and finasteride reverse this process, making hair thicker, longer, and darker.”
That means that if your new hair looks darker than the hair you had before, it’s because it’s healthier. A thicker head of hair tends to look a little darker than a thinning mane. In other words, the color change is a good sign!
If you’ve been researching hair loss treatments online, you might see more guys who use minoxidil talking about their hair changing color.
That might lead you to believe that minoxidil is more likely to change the color of your hair than finasteride, but Dr. Tosti says that’s not the case. (But if your hair is dyed, minoxidil might lighten it a bit.) So, unless you have dyed hair, minoxidil and finasteride are equally likely to affect your hair color.
Nope! “Darkening is a sign of efficacy,” Dr. Tosti says. So if your hair looks like it’s changing color, there’s no need to worry—it just means your treatment’s working.
All of this might not be very reassuring if you liked your hair the way it was. But, according to Dr. Tosti, the only way to get your hair back to its old color (aside from hair dye, of course) would be to stop using your treatment.
“If you stop the treatment, your hair will become thinner and lighter,” she says. “But baldness will also be more evident.”
So going back to your old color also means going back to your old head of hair—thinning included.
Yep, your hair loss treatment can also change the texture of your hair. Dr. Tosti explains that because thin hair tends to be short and curly, it appears frizzy. When hair grow back thicker, the quality improves and it becomes shinier.
To sum all that up, if your regrown hair looks darker than your old hair, it’s probably because your treatment’s working as intended—making your hair thicker and healthier than it was before.

Finasteride is an oral medication used to treat male pattern baldness in men only. It is not for use by women. When used by men, finasteride is generally safe but it can also cause serious side effects, including but not limited to allergic reactions, sexual dysfunction, and high-grade prostate cancer. Most patients find that problems with sexual function resolve when they stop taking the medicine. For full prescribing information, view the drug label information. Photo by Nathan Fertig on Unsplash
