Effective Hair-Growth

Originally posted on marksandspencer.com (UK)

I have used this on 3 areas of my hair for about 2 weeks, now, and have found a definite sign of new hair growth. I am hoping for this to continue.

Yes, I recommend this

Easy to use, light and pleasant fragrance with no oily residue. It seems to be nourishing, but results not evident yet although expecting positive results soon.
