What happens if you deep condition your hair every day
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.
