There are so many hair products out there these days that it's borderline overwhelming, so it's important to know what your hair needs in order to determine which one is right for you. You might be noticing a trend between two different types of treatments and find yourself asking: "Does my hair need protein or moisture?" Luckily, you can figure this out easily enough at home, without having to go to the salon and consult a stylist.
Signs Of Protein Deficiency In Your Hair
It's important to know that protein and moisture treatments deal with two very different issues, but let’s talk protein first. “Hair is a highly complex appendage of the body that is created by many proteins,” Dr. Tara Rao of Schweiger Dermatology Group in NYC tells Bustle. Anabel Kingsley, Brand President and Consulting Trichologist at Philip Kingsley, elaborates: “Think of amino acids (proteins) as the building blocks of your hair; they give strands strength and structure. Without adequate protein, hair can become brittle and fragile.” Some signs of a protein deficiency can be stringy, limp, or sticky hair. “Lack of protein can result in hair loss, and the growth of weak and brittle strands,” Kingsley says, and board certified dermatologist Nicole Rogers, MD FAAD, Assistant Clinical Professor at Tulane Department of Dermatology and in private practice at Hair Restoration of the South, confirms that hair without enough protein “might break more easily.”
Signs Of Too Much Protein In Your Hair
Just like having a protein deficiency, it is possible to have too much protein in your hair — but, again, it’s super rare. “If [the products you’re using] are very protein heavy and the protein molecules in them are too large, they could potentially weigh the hair down and make it feel coated,” Kingsley says. Luckily, this is just a temporary effect: It should clear up as soon as the product is completely washed out.
Signs Of Moisture Loss In Your Hair
In general, if your hair isn’t feeling its best, it’s much more likely that you’re dealing with moisture loss, which most often is caused by chemical treatments (like relaxers and highlights) and hot tools (like your curling iron). If your hair is dry, easily tangled, and weak, it may need more moisture. Kingsley also says split ends, a lack of shine, and inability to hold a heat style could be a sign of dehydrated hair.
Treating Protein Imbalances In Your Hair
Although there are products on the market that claim to be able to restore protein in your hair, most experts agree the real cause of protein deficiency usually has to do with your diet — and therefore, the only way to fix the problem is to make sure you’re eating enough protein. According to Rogers, most people need about 40-50 grams of protein per day, “and have no problem getting it, since the average American actually eats 80-100 grams per day.” Rao agrees that a protein deficiency is quite uncommon: “True protein deficiency that affects hair can be congenital and is identified very early in life,” she explains. “In very rare circumstances, skin, hair, and nails can all be affected by severe deficiency of protein in an adult diet.” Rao also notes that changes in your hair quality can also be a sign of serious illness, so it’s best to check in with your doctor if you’re noticing them. If it is a protein deficiency, “there is nothing that can be added to infuse protein,” Rogers notes. “You just have to grow the hair out.” While you do, you can work with medical and nutritional experts to find healthy ways to add more protein to your diet if they determine you need to.
Treating Moisture Loss In Your Hair
Just like protein, Rogers notes that it’s pretty hard to add moisture back to your hair once it’s been damaged. “Products containing silicone (dimethicone, cyclomethicone) can be helpful to coat and protect the hair shaft, but only temporarily,” she explains. Otherwise, you’ll just need to “grow it out and treat it gently.” As for getting into a regular routine that can help your hair at least feel more moisturized, Kingsley recommends a pre-shampoo conditioning treatment once to twice a week, depending on how damaged your hair is. “These draw moisture into the hair shaft, increasing elasticity, strength, and bounce,” she explains. Kingsley also recommends using a leave-in conditioner to help your hair be easier to detangle and style. Below are some specific products you can try if your hair just isn’t feeling its best.
