Hi Spiriful,
Thanks for our advice. I have been massaging my scalp every night since I read your post. There is no smell at all the next day. How wonderful! It's so soft and manageable. I use shampoo to wash my hair, wash it off with water and then apply urine and massage on my scalp and hair. And will rinse with water thereafter. It feels so good. So soft! Am eager to have my grey hair turn back to it's original color.
