Hair & Scalp Care

Common Questions & Answers
How often you should wash your hair depends on your hair type, lifestyle, scalp condition, and other factors. Overwashing removes too much of a natural oil called sebum, which protects your hair. However, avoiding shampoo can cause other problems.
Seborrheic dermatitis, scalp eczema, and scalp psoriasis are examples of common conditions that show symptoms on the scalp.
Maintaining a nutritionally dense diet, managing stress, and avoiding extreme styling practices can reduce the risk of hair loss for some people. However, preventing hair loss isn’t always possible depending on the underlying cause.
Keratin can repair damaged hair and panthenol may add moisture and shine. Natural oils like coconut, jojoba, and argan oil can also help moisturize the hair. Read product labels carefully to ensure they contain healthy ingredients.
The body needs many nutrients to make hair, and a nutritionally balanced diet supports healthy hair growth. Deficiencies in biotin, zinc, vitamins B, C, and D, iron, and folic acid can affect hair growth and contribute to hair loss.
