Nizoral shampoo is designed to tackle dandruff but many people use it to treat hair loss too.
This review gives four reasons why Nizoral
can potentially treat thinning hair and hair loss symptoms. It also
reveals that this shampoo might actually cause hair loss as a side
Nizoral is a medicated shampoo which contains the drug ketoconazole. Ketoconazole is an anti-fungal agent, and this is why the main use of
Nizoral is for treating dandruff and seborrhea (seborrheic dermatitis) as
explained in the box below.
From the box above, you can see that there's a very interesting link between dandruff and hair loss (androgenetic alopecia). So perhaps it's not surprising to learn that ketoconazole can also help people with hair loss.
Can Nizoral shampoo regrow hair if it’s not even promoted as a hair loss product?
Yes, is the simple answer.
Studies have shown that topical application of Nizoral's active drug ingredient ketoconazole can produce hair growth results comparable to minoxidil (Rogaine) with both drugs being at the same 2% strength (2).
Here are the four ways in which Nizoral shampoo should be able to help if you have hair loss:
1. By reducing yeast levels in the skin. The body has an inflammatory response to the excessive growth of yeast, and this inflammation can affect hair follicle health. So, by reducing yeast levels back down to normal (as explained in the box above) inflammation can subside and hair growth improved.
2. Ketoconazole is also an anti-androgen. Ketoconazole can bind with androgen receptors and so reduce DHT levels in the hair follicles - something that might help hair grow due to the strong link DHT has with hair loss.
3. Less DHT, less sebum. By binding to androgen receptors, ketoconazole can also address the inflammation issue explained in point 1 above. Basically, if there’s less DHT, there’ll be less sebum too (as explained in the box above). And if there’s less sebum to feed the yeast, this should help control both yeast proliferation and the inflammatory response the body has to it.
4. Less sebum, more hair.
In excess, sebum might clog up the follicle roots and contribute
slightly to hair loss. So, if there’s less sebum in the follicles, this
might also support hair growth.
No, probably not.
Since ketoconazole can act against androgens, it seems likely that Nizoral might best be tried only with androgenetic alopecia (male pattern baldness).
However, the disease tinea capitis (i.e., scalp ringworm caused by a fungal infection) can also lead to hair loss which has been successfully treated using Nizoral shampoo.
As for other types of hair loss, it’s probably not going to help, but there have been studies on mice which suggest that ketoconazole can promote hair regrowth. And since I’m pretty sure mice don’t suffer from male pattern baldness, it might just be worth a try.
Nizoral shampoo has 12 ingredients including sodium lauryl ether sulfate (SLES). This is potentially bad news as it can cause irritation for some people.
Obviously ketoconazole is the most important Nizoral ingredient, and the one that sets it apart from any other hair loss shampoo you might be thinking about using.
But, remember, ketoconazole is a drug. And drugs can often lead to complications.
It seems to me that an "occupational hazard" of being a drug is that it causes side effects. And ketoconazole is no exception. Here are some of the side effects Nizoral shampoo could cause if you use it:
* It sounds bizarre but the side effects Nizoral shampoo could cause include hair loss - a symptom that Nizoral can be used to treat!
When taken as an oral drug, ketoconazole can also cause liver damage. But, this is highly unlikely from the small dose you’d get from a topical application of Nizoral shampoo. Even so, clearly you don't want to use Nizoral any more often than you need to.
have shown that effective treatment has been achieved with both 1% and
2% strength ketoconazole shampoo for both hair loss and dandruff when
used two or three times per week. In the UK, Nizoral is sold
without prescription at a strength of 2% ketoconazole. So, if you were
to try this product, perhaps using it just once a week might be enough.
There are loads of great Nizoral shampoo reviews. But virtually all of them are from people with dandruff, which is what you would expect really because Nizoral shampoo is not really intended for use as a hair loss product.
Other Nizoral reviews mention some of the side effects listed earlier, including an increase in hair loss. So, use Nizoral shampoo and you might run the risk of making your hair loss worse!
