Often, you tend to overlook small things that keep damaged hair from repairing, no matter what other steps you take. For instance, sleeping on coarse or rough linen – especially pillow covers – can cause snags at the tips of your hair and lead to hair damage. It is best to use softer fabrics to avoid this. Also, never go to bed with wet hair. Always let it dry out at least 80 per cent before you lie down with wet hair, or it could further intensify damaged hair.
