Yes, neem nail oil works. Buy here. Hang on! Stop. Come to think of it, maybe not that quick...
Neem nail oil does work. It may even be worth the money, that's up to you to decide. But before you buy you should know that you don't need to spend a fortune to enjoy healthy, strong fingernails. Keep reading...
In short, neem oil stops nails from splintering and peeling. In record time, no less.
Why? For once I can't give you specific scientific details here like I do on other pages of this website. Brittle nails is not the kind of disorder where cutting edge medicinal research is done or where a lot of funding is available.
However, you can look at the research that has been done in other areas. Fingernails are an extension of your epidermis, your skin. It's the same with hair. Anything that is good for your skin is also beneficial for hair and fingernails.
Neem oil can work miracles on your skin. It is great for dry and irritated skin, soothing, moisturizing and nourishing it, and it does the same for your fingernails. It is rich in minerals and vitamins that may be missing. It generally improves the health and the immune system of your skin.
If your nail problems are due to nail fungus, some kind of infection or similar disorder, then neem oil will take care of that, too. The anti-bacterial and antifungal properties of neem oil are well researched and documented.
The easiest way to find out how impressive it really is, is to try it. For that you have two options:
For one, you could spend money on a proper neem nail oil that contains neem leaf extract and other oils (which are also good for your nails) and essences and scents and this and that. It's luxurious stuff with a matching price tag.
The alternative is to use plain neem oil. Straight neem seed oil costs a fraction of of the dedicated nail oil and can do the same job. You should dilute it 1:10 with another oil or lotion (do not use pure neem oil om your skin!) so a small bottle goes a long way.
Apart from the extra work of diluting it for use, pure neem oil has one more drawback: it does not smell pleasant (to put it mildly).
The good news is that you don't need to use it for long. It works very quickly and your nails will stay strong for several weeks even after you discontinue the use of neem oil. At least that is the experience my friends had. (No animal testing here, I only test on friends and family.)
Neem oil has so many uses that you'll find a million things to do with the rest of the bottle. You may even want to get a bigger bottle. That makes the use of straight neem oil a very economic solution.
On the other hand, if you can afford it, if you don't want to mess around with mixing your own ready to use nail oil, if you are concerned about the smell or if you are around people all the time, then you may prefer to spend extra for the better smelling and ready to use neem nail and cuticle oil.
Just massage a drop or two into your fingernails and cuticles. If using pure neem oil try to mask the odor by putting some nicer smelling lotion over the top. (It works somewhat.)
Do it twice a day and you should see improvements very quickly!
