This easy, step by step plan will teach you what products to use, and how to apply conditioner like a pro. First though, I want to give you a list of supplies you'll need, and a little information about hair. Each strand of hair has 3 layers.
Deep conditioning affects the outer layer which is called the cuticle.
The cuticle resembles shingles on a roof. They overlap each other, and should lay down flat. When your hair becomes dry and damaged, these shingles will stand up away from the hair shaft. This is what gives hair the dull, frizzy look. Deep conditioning the proper way and with the right products will help to smooth the cuticle, making the shingles lay down again, giving your hair a smoother, shinier, healthier appearance.
