Using a preconditioner on your hair before using a shampoo helps you nourish your hair. It moisturises your hair and even after using a shampoo, your hair stays soft and shiny. The idea behind preconditioning is to moisturise your hair before the shampoo strips the natural oil from the tresses.

It's not a bad idea to try and use moisturizing products across the board, but, at the very least, incorporate a moisturizing deep conditioner or treatment into your routine once per week, Wellman advises. A few key ingredients to seek out: Shea butter, avocado, glycerin, and aloe, all of which are deeply moisturizing.

How does deep conditioning work? It gives your hair a big hit of moisture or protein, helping to strengthen your hair at the cuticle. A mask can reduce breakage and split ends, improve elasticity, and keep your hair healthy.

Depending on the condition of your hair, you should use a deep conditioning treatment around once a week. However, if your hair feels dry and stressed, you can use them up to 2-3 times a week.
