If your hair is damaged or lifeless, you can look to a variety of factors as the culprit: environmental toxins, product buildup, over-styling, coloring and perming, lack of internal care…you may also be using products that are not suitable for your hair type and/or its current condition.

Damage cannot really be undone, but you can certainly help your hair look its best until the damage grows out. First, determine whether or not your hair is damaged by taking a strand out from the root and examining it. Hold hair at each end and pull, if it stretches you have healthy hair. If it breaks easily, it is damaged.

For overly dry or damaged hair from styling and over-processing: Look for deep conditioning products that have “protecting, nourishing and replenishing” ingredients. Try Macadamia Deep Repair Mask.

For fine or limp hair: Use volumizing products and light conditioners. Massage scalp vigorously in circular movements when shampooing to stimulate the scalp, then blow dry hair upside down to create a boost at the roots.

For dry, brittle or curly hair: Find “controlling” products with added shine and moisture. Our favorite? Weleda Rosemary Oil.

For frizzy hair: Thick, coarse and curly hair are prone to frizz, particularly in hot and humid weather. Letting conditioner soak in for at least five minutes prior to rinsing will help. Comb with a wide-tooth comb and let air dry, avoid combing or brushing hair while dry. Apply a couple drops of anti-frizz serum to wet hair. An anti-frizz shampoo and conditioner duo we love: Brazilian Blowout Acai Anti-Frizz Shampoo + Conditioner.

For dandruff-prone hair: Wash with shampoo containing salicylic acid, selenium sulfide and rinse thoroughly. Avoid alcohol-based styling products. If problem persists, seek medical attention from a dermatologist as psoriasis or seborrhea dermatitis may be to blame. The crème de la crème of anti-dandruff shampoos?
