Not your usual oil infused conditioner that weighs down your hair after a single wash. No. Tresemmès expert keratin smooth marula oil conditioner gently nourishes the hair from root to tip without the greasy look. I conditioned my hair for 3 minutes after using the expert keratin shampoo and I felt my hair detangle immediately. The results left my hair full of life , shiny , frizz-free and feeling silkier than ever.
