When working with porous hair, what product characteristic should be chosen?

• A. Lower alkaline content
• B. Higher alkaline content
• C. No pH consideration
• D. Neutral pH

Answer: (A)

Porous hair has a more open cuticle and readily absorbs moisture and chemicals. Alkaline formulations lift the cuticle, allowing deeper penetration, which in porous hair can lead to excessive swelling, uneven processing, and more damage. Using a product with lower alkaline content helps keep the cuticle from lifting too much, reduces swelling, and protects the hair structure while still allowing the chemical to work effectively. So choosing lower alkaline content is the gentlest, most protective option for porous hair.
