Some causes of brittle, limp hair are as clear as day (like your 400-plus degree heat setting!), but others are not as obvious. For example, hopping in the shower or going for a dip in the pool can actually do more harm than good if you’re not taking the right precautions to protect your hair. Keep your strands silky smooth and, more importantly, healthy by avoiding the dry-hair contributors below.Steamy ShowersShowering with hot water can strip moisture out of hair and leave it limp and dry. Instead, wash and rinse using lukewarm or cool water to seal strands and lock in moisture. Your ShampooNot all shampoos are created equal. Some formulas contain sulfates, which strip away more than just dirt and oil buildup — they can also remove the natural oils your hair needs to stay healthy and hydrated. For a sulfate-free option, try the Garnier Whole Blends Sulfate Free Remedy Honey Treasures Shampoo.Towel DryingThe friction from roughly towel drying your hair causes breakage and overall dry, frizzy strands. Instead, use an old cotton T-shirt or microfiber towel to absorb excess moisture without the damage. If you have curly hair, take an extra step while hair is still damp, and comb a leave-in cream, like Carol's Daughter Monoi Leave-In Cream, through your strands to protect from breakage.
