The first step in this is to know what is your hair type and choose hair conditioner according to that. Try to find out your hair type conditioner so that it will nourish your hair and make them more shiny and strong.
Never apply conditioner on the roots
Conditioners are lotions for your hair and have no business to be on your scalp. Furthermore, your scalp is equipped for making its own particular oils so it is best to apply the conditioner an inch far from the roots, uniformly all through the body of your hair right till the very end.
Let it stay on
Allow your conditioner to stay on and give it time to moisturise your hair. Depending on the length of your hair you must leave it for long. Say for very long hair, allow it to sit for 5-8 minutes.
Keep rinsing till the water runs clear of any bubbles or conditioner residues. This is important for the simple reason that any residue left on your scalp can cause hair fall.
