This is what it says on the back of my bottle of Mega Tek Rebuilder:
Manes & Tails: Revitalizes hair so mane and tail won't break off as easily and will grow longer. Continuous bare spots caused by blanket rubs, skin conditions and injuries.
Directions: Apply to wet clean hair. Leave on 5 minutes then rinse off. Meg-Tek can also be left on for continuous benefits, such as putting on tail and wrapping it. Does not have to be rinse off. Use as often as possible, usually 2 or 3 times a week or whenever horse is bathed. On injuries, skin problems or blanket rubs, use daily. Use a small amount on dry or wet coat.
Ok, so if I didn't have this weave in, I would probably put it on at night, wrap with a plastic cap, sleep in it, then rinse it out. Then I would probably use just a hand full and massage in my scalp, and bun up. I would probably do this every day for a week, undiluted. You know, give my hair and scalp shock trauma for a good head start of growth.
