Keeping hair hydrated is one of the most important things you can do for healthy hair, so moisturizing dry hair overnight is a great way to do with minimal effort. Luckily there are a lot of ways you can accomplish this so you can definitely find a method that will work for your hair type.


When you’re sleeping is actually a great time to take care of your hair, and protect it from further damage. This post will give you a good routine you can implement every night for hair that will gradually become more moisturized, shinier, and healthier overall.


What does dehydrated hair look like?

Dry hair is dull and lacks shine. Over time, dry hair becomes weak and brittle and is at risk for breakage. Dry hair can cause split ends, which is when the ends of your hair appear frayed like the end of a rope. Once split ends appear, they can be minimized with hair products but not fully repaired. Keeping your hair moisturized will prevent your hair from breakage and split ends.


How to Moisturize Dry Hair Overnight

Use one or a few of these steps to moisturize your hair while you’re sleeping and wake up with healthier, shinier hair. 

1. Use a leave-in conditioner

Leave-in conditioner is great for adding extra moisture after you leave the shower. It works to deliver moisturizing ingredients and hair-healthy oils and vitamins to your hair without you having to wash it out. After you’ve washed and conditioned your hair in the shower, towel dry your hair. Once it is still damp, spray leave-in conditioner throughout your hair and brush through with a comb. 


Leave-in conditioner works for all hair types. There are lightweight products for fine hair as well as more deeply moisturizing leave-in conditioners for thicker hair types.


2. Seal it with oils

Sealing the ends of your hair is a popular technique for curly-haired types, but anyone with dry hair and dry ends can try this technique. After you’ve washed your hair take your favorite hair oil and apply it to the ends of your hair with your fingertips.

Start out by trying this once a week. If your ends are still very dry thoughout the week, bump it up to twice a week. You can also try this on dry hair.


3. Lock in moisture with a bonnet or silk cap

If you are going to put a moisturizing product in your hair overnight, it’s best to lock in the moisture with a silk cap or bonnet. These caps will help retain moisture, making sure your hair doesn’t dry out fast while you sleep. They’re also great for preventing tangling, breakage, and frizziness, so they are multi-tasking healthy hair heroes. 


4. Try a homemade deep conditioning hair mask

Deep conditioning hair masks are not something you’ll want to leave on overnight, especially if they contain protein. Here’s a great hair mask recipe you can make at home and leave on overnight:

  • 2 ripe bananas
  • 1 tbsp honey
  • 2 tbsp coconut oil

Mix these together until it is smooth and apply to your hair starting from the roots and going all the way to the ends. Wrap your hair in a cap or t-shirt to protect your bedding. In the morning, wash out the mixture and your hair should already be feeling noticeably soft.


5. Use an overnight serum

Overnight serums are products specially made to moisturize dry hair overnight. These easy-to-use serums are meant to be applied to your mid-lengths and ends.

Covering your hair with a silk cap is a good idea to protect your hair, or you can tie your hair in two loose ponytails on the sides of your head to keep your hair from moving too while you sleep. Some overnight serums will require you to wash out in the morning where others will not. 


Can I leave moisturizer in my hair overnight?

Most hair masks that are made to deep conditioner and moisturize the hair should NOT be left in your hair overnight. Most hair masks are meant to be left in your hair for anywhere between 5 and 20 minutes and then washed out. Ingredients like apple cider vinegar and any sort of protein can case your hair to become even dryer if left in your hair for too long. Make sure the products you leave in your hair are safe for overnight use.
