After shampooing, generously apply DOO GRO® Mega Thick® Intense Repair to wet, damp or towel dried hair. Gently finger comb or massage through hair. Leave on 1-3 minutes. For deeper conditioning, leave on 5-15 minutes (use of heat cap, plastic cap or hot towel will increase effectiveness but is not required). Rinse hair thoroughly. Style as usual. For best results, use the family of DOO GRO® Products.
