What are the characteristics of alkaline hair products?

• A. They have a low pH and close the hair cuticle
• B. They have a high pH and can open the hair cuticle
• C. They are suitable for all hair types
• D. They are hypoallergenic and fragrance-free

Answer: (B)

Alkaline hair products are characterized by their high pH levels, which typically range from about 8 to 14. This increased alkalinity causes the hair cuticle, the outermost layer of the hair shaft, to lift or open up. When the cuticle is opened, it allows for better penetration of the product into the hair shaft, making alkaline products particularly effective for chemical treatments such as permanent waves, relaxers, and coloring. The function of these products hinges on this ability to open the cuticle, which is crucial for processes that require deeper absorption into the hair. This is why they are often used in situations where significant change is intended, such as altering the structure or color of the hair. Understanding the effects of alkaline pH on hair structure is essential for anyone working in the field of cosmetology, as it informs the proper application and choice of hair care products based on the specific needs and conditions of the hair being treated. In contrast, products with a low pH are designed to close the hair cuticle, maintaining moisture and shine in the hair, which is not characteristic of alkaline products. Additionally, not all hair types are suitable for alkaline treatments, and while some products may be hypoallergenic or fragrance-free,
