I can assure you that I will use the topknot the rest of my life along with the annoiting oils. With out these my hair would be grey. Just a few squirts on my temples maybe once a week or every 2 weeks and my grey is gone. I use the annointing oil about once a month now. Both bottles will last long past a year when used correctly.
"IF" I had to do it all over again? The Topknot would be a alcohol tincture formula in a 2 ounce spray bottle. This would last a year. The 8 ounce tincture/syrup bottle is probably better as a tea to drink, which Christopher's original method was a tea drink wash method. Some people get confused and spray the topknot all over their hair and this will be sticky because of the glycerin. So in the future you may see the big 8 ounce bottle discontinued and the better way someday.
The Topknot has a little of the anointing oils in it for those that never try the annointing oils because of the high price of such oils.
The Topknot Blond is a very unique formula that still fasinates me.
Every herb formula can be made better and with age they even get better yet.
