How to wash your hair extensions

1. Use a wide tooth comb to comb out the hair extension. This prevents breakage and forming of knots.

2. Wet the hair gradually from top to down. Wetting the hair at once will make it entangle.
3. Dissolve a shampoo (recommend organix products) in warm water and dip the hair extension inside. Leave it for 15 minutes. Do not turn it while in water or it will tangle. Always use shampoo that will not dry out the hair.
4. Rinse to remove the shampoo and dirt. Scrubbing will cause tangling.
5. Now apply a good leave in conditioner (recommend organix products)
6. Wrap the hair extension in a dry towel and gently squeeze to remove excess water.
7. Let the hair air dry.
8. Comb out hair once it is dry using a wide tooth comb
9. Hair is ready

No 5 says apply leave in conditioner you didn't say we raise it after applying the conditioner
