Let's talk about moisture and protein.
It wasnâ€™t until I decided to make a spontaneous salon visit a few weeks ago (oh, that fateful day) that a wise stylist told me that despite my efforts, I had actually been starving my hair all along. She taught me that healthy hair requires two thingsâ€”moisture and proteinâ€”and that hair treatments are not one- size-fits-all. Some provide moisture exclusively while others offer protein, and knowing which your hair needs may be the difference between lifeless and vivacious locks.
Moisture vs. Protein: The Science
The difference between protein and moisture starts at the atomic level. Each strand of hair is held together by something called disulfide bonds. Proteins reinforce these bonds, making hair stronger and less likely to break. On the other hand, moisture contributes to the overall look and feel of your hair. According to celebrity colorist Matt Rez, â€œThe protein bonds are what keeps the hair shaft together and strong. Without it, your hair will break or snap. Moisture is hydration and what keeps the hair soft. Put the two together, and we have healthy hair!â€
Think of it this way: If the mere act of brushing your hair causes snapped strands and fallout, you may need a protein treatment. If breakage isnâ€™t your issue, but the feel of your strands is dry and wiry, youâ€™re likely lacking moisture.
How to Tell What Your Hair Needs
Thankfully, it's easy to figure out which treatment your hair needs. Rez recommends performing a simple at-home test: â€œWhen the hair is wet, pull a strand,â€ he says. â€œIf it stretches and then snaps, itâ€™s most likely porous, meaning it is dehydrated! That is a moisture issue. If the hair doesnâ€™t stretch and immediately snaps, you need protein to rebuild its structure from within.â€
After finding out that pulling on a piece of my wet hair could potentially end my years-long hair woes, I immediately ran for the nearest sink. Much to my surprise, when I pulled on a strand, it stretched and stretched and stretched. It took real effort to actually snap the strand. So thatâ€™s why my beloved hair masks werenâ€™t transforming my locks like they used to. All along, Iâ€™d been giving my hair protein when it needed moisture. Right then and there, I promised my thirsty hair that I would pick up a mask or treatment after work.
Rez, to my delight, had some suggestions. He applauds Shu Uemuraâ€™s Moisture Velvet line (No Longer Available) for its intense hydrating capabilities. If protein is what you need, he recommends the brandâ€™s Ultimate Reset line. However, if your breakage is quite severe, turn to haircare heavyweight Olaplex. â€œItâ€™s genius,â€ says Rez. â€œIt rebuilds the disulfide bonds that are the primary structure of the protein.â€
If you bleach or lighten your hair, you likely can benefit from an Olaplex treatment anyway, as lightening hair involves damage throughout entire hair cuticle.
Recommended Products and Treatments
I love product recommendations, but I was also curious about DIY remedies: Was my coconut oil habit treating protein or moisture loss? Surprisingly, Rez says a little bit of both. â€œCoconut oil and other virgin natural oils like grape-seed oil have healing properties, and they can help hair feel softer and sometimes stronger depending on the severity of damage or dehydration,â€ Rez says. Evidently, coconut oil is one of the only oils that can help repair protein loss, as well (here is where I did a little happy dance, learning my coconut oil obsession wasnâ€™t without merit).
