“This product has worked well for me for a number of years now. My mother had to wear a full wig by her early 50s and my hair started to really thin in my late 50s. I was so glad that after the 4 months advised it would take, my hair thickened up again. I did try using a once a day treatment but it was dispensed as a foam which didn't seem to get to my scalp as well as the twice a day dropper. Some reviews say it makes one's hair greasy but it has never happened to me.”
