19. Caffeine Shampoo
This growth treatment requires caffeine powder – and believe me, it definitely gives your hair a serious wake up call!
You can use the shampoo as requently as you like;
in no time at all, you'll see some serious growth!
Recipe: Mix 4 teaspoons of caffeine powder in eight ounces of shampoo and suds up as usual. You can also mix the caffeine powder in a spray bottle with eight ounces of water, and spritz it on 10-15 minutes before showering.
How Often: You can use this treatment each time you shampoo, but don't use it more than once a day. Protip: if you start experiencing headaches, you're using too much spritz or shampoo. Stop for a few days (or up to a week), then try again using 2-3 teaspoons of caffeine powder instead.
Where to Buy: Caffeine powder is available at most health and wellness stores, several retail stores, and at many shops online, including Amazon.
