Which hair mask you use all depends on your hair type. You should consider the quality of your locks as well as the level of damage on your mid-lengths and ends. Let's take a look at the professional's advice on using hair masks.
When you head to your local department store or salon for your monthly stock-up on products, you need to ask yourself the following questions: 'Do I want to nourish, hydrate or add shine to my locks? You need to identify what your hair needs in order to select the correct mask'.
Generally, women tend to use hair masks because their hair has become damaged. 'Masks restore and repair the hair's fibres. For optimum results, apply regularly over a certain period of time. If you have chosen the correct mask, your hair should appear replenished and in better condition after the very first use'.
If your locks are damaged, you should be using a mask every other day to remedy the problem. 'If your ends and lengths are super dry with lots of split ends, apply daily after your regular shampoo. Masks tend to absorb quickly into damaged hair as it is naturally more porous, however as time goes on the fibres should be repaired and strengthened'.
Our advice: Hair masks can weigh down the hair if applied incorrectly. Avoid the root area at all costs! Focus on the mid-lengths and ends instead. The only exception to this rule is if you have selected a mask designed to eliminate greasy roots or a volume-enhancing formula.
