I stopped loosing hair the day I started deworming. I will guess the average male age 30 starts loosing 20+ hairs every day they shower.
I believe more today that hair loss is a fungal problem. I have about 5 gallons of TOPKNOT left and when I make my second batch, I plan on adding the Natural tree Iodine and also make it much stronger, much more consentrated so most likely it will be in a 4 ounce spray bottle. I am still using the Topknot with perfect results, but after making a first batch, there is always room for improvement of any formula.
