Deep conditioning overnight? Let’s figure out whether it is good or not!

What Happens If You Leave Conditioner In Your Hair Overnight

When we undergo various hair care procedures (no matter at home or in a salon), we hope that they will have a visible effect soon enough. Of course, all of us would like to see our hair glossy, healthy, and strong the next day after we apply that magical conditioner or any other product that promises us wonderful results! And this is why some girls decide that “the more the better” concept is exactly what can make it happen.

This is why there are so many questions about leaving a conditioner in hair overnight. Simply because most women believe it can help to get a desirable effect faster! But is it really so? And is it bad to leave conditioner in your hair like this? This is what we are going to figure out today.

What Happens If You Leave Deep Conditioner In Your Hair Overnight?

Simply speaking, sleeping with conditioner in hair is not recommended and even prohibited. Hair conditioners, and especially the deep conditioning products, come with the instructions for a reason.

It may seem that, if we leave hair conditioner in our strands during the night, the effect from this product will show up faster and will be more prominent. However, it is a huge mistake to think so! You would not take more than the prescribed dosage of medication just to make it work faster, right? Right, you would not because you know what the aftermath can be if you do so!

It is all the same with hair care products including conditioners. Practicing deep hair conditioning overnight can end up with quite an adverse effect on your tresses. See, deep hair conditioners are formulated to penetrate the hair shaft to be able to cure dry and brittle hair. According to the tests taken, you normally need to let the hair conditioner sit on your chevelure for fifteen to thirty minutes to allow the product to work as it should and moisturize your hair properly.

But if you leave in the conditioner overnight, this is what will happen to your hair. The moisture will be absorbed into the hair shaft making the inner hair structure – the cortex – swell. This will create tension on the hair shaft as it expands. And as your hair dries, it contracts back to normal.

However, since the product is there on your hair all night long, your tresses will undergo the constant expanding and further contracting. And this is definitely what they are not meant for! Such fluctuations will lead to what is called hair cuticle hygral fatigue. Simply speaking, too much moisture absorbed into the hair cuticle may force it to become way more fragile and lose its elasticity over time. That’s if you practice overnight deep conditioning regularly.

The repeating stress after the constant wetting and drying can even result in hair breakage!

  • Rinse the product off with room temperature water

What Does Deep Conditioning Do to Your Hair?

Have you ever asked yourself this question? We are pretty sure you have! And if you haven’t found the answer yet, we are here to provide you with it. See, in general words, hair conditioners are made to make your hair feel softer, lustrous, and manageable.

These products contain cationic surfactants. These surfactants have positively charged hydrophilic heads that stick to the negatively charged hair strands and form a sort of protective coating that reduces static electricity and friction. In addition, hair conditioners improve the shine and color of our strands.

What to Do If You Notice the Symptoms Of Hygral Fatigue On Your Hair?

As you already know, excessive hair conditioning may lead to hygral fatigue. But how do you know that your tresses are affected by it? Simply check your hair for one or several of these symptoms:

  • tangling
  • frizziness
  • dullness
  • brittleness
  • constant hair breakage
  • a gummy texture

If you notice that you have it, don’t panic. Hygral fatigue can be treated quite easily, and you can start with one of the suggested solutions.
First of all, try to change your hair product and washing routine. If the reason for your hygral fatigue is over moisturized hair, minimize the use of shampoo and conditioners, and also reduce the frequency of hair washes.

Also, if you reduce other sources of damage, it may help a lot. What do we mean? Don’t towel-dry your hair, stop chemical treatments, straighten your hair less, use blow dryer less frequently, and avoid dyeing your chevelure too often.

And follow a few simple rules to be able to avoid the development of hygral fatigue in future:

  • shampoo your hair gently
  • wear a swim cap when in a swimming pool
  • after washing, let your hair dry itself before you brush it
  • use shampoos with a low pH
  • apply coconut oil as a pre-wash

With that in mind, you will restore the health of your tresses and your hair will be thick, healthy, and strong again.
