Vitamin E is loaded with antioxidants. Mix some Vitamin E Oil with Coconut Oil and Olive Oil and you have a nice punch to moisture and getting rid of unwanted scalp problems.
Coconut Oil contains great fatty acids that have properties of antimicrobial, antibacterial, antiviral, antifungal, and offer free-radical-fighting antioxidants. This allows Vitamin E Oil to work that much better.
Olive Oil is a good staple to add a moisture packed punch. (EVOO)
Another great combo to use is Cinnamon or Cardamom with a nice rich dark honey is a super punch for stimulating hair growth also and naturally lightens hair over several uses. (Some people have sensitivity to Cinnamon, so Cardamom is actually safer)
I have thinning hair myself and I've seen nice results with the Cinnamon and Honey. Honey is also a nice natural humecant which attracts moisture.
There is a whole library if oils and natural items you can use on your head, skin, and face. LOL.
Now specifically I do not know about Now products other than the fact reviews say the quality is lacking for making items with. *shrugs* it's cheap though.
I buy a lot of my oils from Fixed Oils | Bramble Berry® Soap Making Supplies
There are a ton and it gives you a nice list that you can google the affects of an oil that could help.
Lastly, massaging the scalp to stimulate circulation is a must.
That's all I got! LOL I hope this helps you.
