The Best Deep Conditioning Caps

Are you dealing with bleached, frizzy, dull, or altogether unsightly locks? A deep conditioning treatment can help restore much-needed moisture and vitality back into your hair to make your mane really shine. But a deep conditioner alone isn't enough for your at-home haircare session. You'll also need a deep conditioning cap. A deep conditioning cap provides an application of heat straight to your scalp, which in turn helps to open up your hair follicles. This allows your strands to get the most out of your deep conditioning treatment. The result? Hair that looks like you just came from the salon – or stepped off the pages of Vogue. Here are the best deep conditioning caps available to keep your mane looking fresh and amazing.

Frequently Asked Questions

What is a deep conditioning cap, and how does it differ from a regular shower cap?

A deep conditioning cap is similar to a shower cap, but it’s thicker and is specifically designed to improve the effects of your deep conditioning treatment by using heat. This heat helps allow your conditioner to more deeply penetrate your hair follicles and scalp.

How do I use a deep conditioning cap?

Before starting your at-home deep conditioning treatment, be sure to thoroughly wash your locks and apply your deep conditioner to every inch of your hair, from root to tip. To use your cap, you’ll first need to put it in the microwave to heat things up (read the directions thoroughly before doing so). Then, pop your cap on and let the moisturizing magic begin.
