The effectiveness of minoxidil for bald spots

Minoxidil is a useful product in the fight against hair loss, and can even be used to regrow some lost hair.

Nevertheless, even this potent drug’s effectiveness has its limits. Important to realize is that the sooner you start using minoxidil once you start noticing hair loss, the better your results will be.

The reason being that it’s much easier to halt or slow down hair loss than it is regrowing lost hair.

Let me explain if using minoxidil for bald spots is effective or not.




Does minoxidil work for bald spots?

Using minoxidil for bald spots will probably not be very effective.

It’s currently hard, if not impossible, to regrow lost hair in areas with dead hair follicles. And as fate must have it, hair follicles are a requirement in order to be able to stimulate them to have a chance at regrowing hair.

However, if there’s still some hair present in those otherwise bald or balding spots, then that’s a sign that your hair is thinning, but that there’s still hair follicles that are alive and kicking. If that’s the case, then minoxidil can most likely excite the hair follicles that are still alive. Minoxidil can even be effective at treating stress related hair loss.

Can hair regrow in bald spots?

We can conclude that using minoxidil for bald spots will probably not be effective. As a matter of fact, it probably won’t do much at all.

Nevertheless, I would say that it’s still worth trying. Most people tolerate minoxidil very well with minimal to no side effects. It’s a relatively cheap, affordable, and convenient way to attempt to grow hair on the bald spots instead of looking at more expensive and invasive alternatives such as a hair transplant.

At worst, you can still quit after a few months if you notice no improvements in the number of hairs or hair density.

But beware. The longer you decide to quit minoxidil, the more hair loss you will experience.


What causes small bald patches on head?

If you have small bald patches on your head, then it’s most likely due to one of the following reasons:

  • Alopecia Areata
  • Progressive pattern hair loss

If you have one, or multiple small bald patches on your head, then chances are large that it’s due to Alopecia Areata. Alopecia stands for bald, and Areata stands for patchy.

Alopecia Areata is an autoimmune disorder that causes your hair to fall out in some, or multiple, areas of your body due to the autoimmune system attacking the hair follicles. It’s not just limited to the hair on your head, either.

The hair that falls out is often in chunks, and around the size of a quarter.

Why do I suddenly have a bald patch?

If you have sudden bald patches on your head, or anywhere else on your body, then it’s most likely that you’re suffering from Alopecia Areata.

Alopecia Areata can have multiple causes, although the reason why it occurs is not well understood.

Severe stress and a genetic predisposition to develop Alopecia Areata are both risk factors for getting bald patches.

Fortunately enough, the bald spots are typically transient in nature.


Do alopecia spots get bigger?

Alopecia spots can get bigger, although most certainly not always.

To tell the truth, most of the time the hair loss that happened due to Alopecia Areata resolves, and the hair in the bald spot, or multiple bald spots regrows within the first few months of onset.

Even so, it’s possible that small Alopecia Areata spots keep growing bigger with time, and that multiple patches can merge together to create one large bald spot that can resemble progressive pattern hair loss.

Fortunately, this is an exception rather than the rule. But it can happen nonetheless.



While minoxidil is efficient to combat progressive hair loss, it’s not nearly as effective to regrow lost hair of completely bald spots on the scalp if the cause of hair loss is male/female pattern baldness.

If the cause of losing hair is Alopecia Areata, then results are generally favorable, since it’s usually a temporary disorder. This means that it’s likely that the bald spots will go away on their own, and new hairs will start to grow in those same spots in the first few months.

The key is to not let progressive hair loss advance. It should be treated as quickly as possible with over the counter treatments such as minoxidil and microneedling in order to prevent bald spots from occurring.
