(female)
I’ve been using Minoxidil for about a year. It seemed to stop my hair from falling out, with new regrowth. But, my hair is so fine now; the strands are very thin, that gains seem to have been replaced with thin fragile hairs. Is this typical? If I stop using it, will the strands that grow back stay fine, or thicker as they were before? Any comments on weight gain, as a small percentage side effect? Thank you so much!
If you stop using it and if your hair is minoxidil dependent, then you will lose hair along with whatever benefits you’ve gotten since you started the medication. I don’t know how much regrowth you saw since I don’t have before and after photos of your hair, but you need to continue using the minoxidil for life in order to maintain the gains you made.
Fine hair is fine hair, but minoxidil did not cause that. Minoxidil doesn’t change the character of hair. Fragile hair occurs in some people, but you might check with your hair stylist for a solution to this one. Remember the hair that you are treating with minoxidil is fragile by its nature if it is miniaturized due to the genetic balding, so I would imagine that your minoxidil treated hair will be easily broken if you are rough in handling it.
Female hair loss is tricky, and there are many possible reasons for the loss you see. If you were diagnosed with genetic loss by a doctor, that’s one thing, but if you are just treating yourself, there are common blood tests you can have done to see if there is another potential cause (see here).
Why a strand of hair bends or falls the way it does may sound like a simple question, but the answer is rather convoluted. On one level, the texture of a person’s hair derives from his or her genes. A 2009 study looked at the genetics of waves and curls and reported a heritability of between 85 and 95 percent. (That means about nine tenths of the variation in hair texture within the sample could be ascribed to DNA.) How does this play out at the level of a single hair? Research shows that the curvature of a strand depends on the nature of its follicle. When a follicle is asymmetrical, the hair that it produces is oval in shape and tends to curl. When it’s symmetrical, the strand that emerges grows round and straight.
