Okay, let’s get right down to business. A leave-in conditioner (as the name suggests) is a conditioning treatment that is left on the hair after you apply it and doesn’t need to be washed out. Why, you ask? Well, the reason behind the leave-in formula of these conditioners, is that it continues to provide conditioning benefits throughout the day.

If you’re thinking that just because your hair doesn’t need extra hydration that means a leave-in conditioner isn’t for you, think again. The truth is, no matter your hair type or hair length, a leave-in conditioner can do wonders for your mane.

Why You Need a Leave In Conditioner:

Many of you may have been under the impression that a leave-in conditioner only has a single purpose—to condition hair without being rinsed off. But in reality, these wondrous products have a wealth of advantages for your mane, so take a look below at the several ways your strands can benefit:

1. It adds extra moisture.

If your hair is feeling especially dry, give it the TLC it deserves by using a leave-in conditioner. Not only will it give your hair the extra moisture it needs, but will also leave your hair feeling incredibly soft and smooth.

2. Aids in detangling.

Do you face a daily battle of detangling your hair in the morning? If you find that your tresses become knotty and unmanageable after washing, using a leave-in conditioner can make the world of difference, providing extra slip in your strands and thus reducing the amount of breakage often produced by brushing.

3. Helps the look and feel of damaged locks.

For those among us who struggle with brittle locks, leave-in conditioners are a real game changer as they can help smooth damaged hair to improve the look and feel of your mane.

4. Preps hair for styling.

If you use heated styling tools regularly, you can rest assured that not only will your leave-in conditioner moisturize and nourish your hair, but since it also acts as a primer, it can help add a layer of protection to strands too.

However, for blow-drying, straightening or curling wand addicts, we would suggest doubling up with a good heat protectant as an extra safeguarding measure!
