Step-by-step explanation:
The two basic requirements for a healthy scalp are proper nutrition and hydration, and avoiding excessive heat and chemical treatments.
Proper nutrition and hydration are important for maintaining healthy hair and scalp. Nutrients like vitamins and minerals are necessary for hair growth and maintaining scalp health. Drinking enough water and eating a balanced diet that includes foods rich in vitamins A, C, and E, omega-3 fatty acids, and biotin can promote a healthy scalp.
Excessive heat and chemical treatments, such as using hot styling tools or harsh hair products, can damage the scalp and lead to dryness, irritation, and even hair loss. It's important to avoid excessive heat and chemical treatments and opt for gentle hair care practices and products.
