This is the hair solution that will help your hair grow in areas like your crown, temples etc. This product is brand new and was never used. I bought it and could not use it. I did not know that it had an oil base until I opened top and visually realized it. I have extensions in my hair and I can not use it. I believe it would have worked. I don't doubt it for a second because it contains minoxidil. I can't use it because of the oil base. So upsetting, because I was looking forward to it. I can not return it as the company does not offer guarantees. So I figured I would put it on here and offer it to someone else who wanted to try it. It can be applied to scalp at night and wash it out in the morning. It's definitely worth a try if you are thinning, male or female.
