DO Brush your hair extensions on a regular basis to ensure they do not matt
DO Ensure you thoroughly rinse all traces of shampoo and conditioner after washing your hair
DO Invest in a good extension brush and an extension detangling comb
DO Be extremely gentle with your extensions at all times
DO Keep extensions tied up during swimming (both pool and sea), if you do get your hair wet you must ensure you rinse out any chlorine or seawater as soon as possible as they can cause your extensions to dry out, in the same way they dry out your own natural hair.
DO Tie your extensions back at night, preferably with a loose plait or ponytails to minimise any tangles in the morning.
DO NOT tie your hair back too tightly, this can pull on the bonds causing them to weaken.
