For the past two weeks, I have washed my hair three times per week. My weekend wash includes a deep condition whereas the washes in the week are simply a shampoo and conditioner wash.
The major change I have seen in my hair is fewer small pieces of broken hairs. Length retention has been a challenge for me for so anything that can help prevent my ends from breaking off is much appreciated. I think my hair appreciates the extra moisture I get from wetting my hair three times a week. If I can keep my length retention on point, then I am going to see changes in length.
I will keep monitoring my hair from week to week to see if I notice any untoward consequences from wetting my hair so frequently. So far, so good, however.
