What Happens If You Deep Condition Your Hair Every Day

Deep conditioning your hair can be addictive (though you definitely want to make sure you're doing it the right way). Not only is it the secret to making your locks look and feel better than ever, it's an important step in any haircare regime, and is something we should all be doing at least once a week. 


"Using a deep conditioning treatment adds moisture back into hair, which helps it to become stronger, healthier and shinier," Rita Hazan, celebrity colorist and owner of Rita Hazan Salon in New York City, told InStyle. "Between shampoo, straightening, and blow drying, you have to add nutrition back into the hair after torturing it," she added. 

But unfortunately, there is such a thing as too much deep conditioning or over-conditioning. Here's what happens if you deep condition your hair every day.

Over-conditioning can cause problems

According to Lizzie Carter, director of Only Curls, over-conditioning can cause 'hygral fatigue'. "This is where excessive and repeated swelling of the hair cuticle causes the hair to stretch beyond what's normal," Carter explained to Cosmopolitan. "Over time, this can result in the hair becoming more fragile and less elastic. If your hair is looking limp and lifeless it could be over moisturized."


Ultimately, when it comes to how often you should be deep conditioning, it really depends on your hair type and length. For example, those with curly hair may need to deep condition their hair more often than those with fine hair, as curly hair is known to be more prone to dryness (via Good Housekeeping). 

If you are deep conditioning more than once or twice a week (or every day) and notice that your hair is looking oily and flat, Carter recommends cutting back on deep conditioner and opting for a protein treatment instead. Don't be afraid to reach out to your hairstylist to discuss what will work best for you then experiment with frequency until you achieve the optimal result.
