L'Oréal Professionnel Inforcer Strengthening Shampoo - Prevents Breakage and Adds Softness For Weak, Fragile & Damaged Hair Types, With Biotin

This is the shampoo I regularly use. I love that it has Biotin in it that is good for strengthening your hair.

Shampoo Basics & Tips

Why Biotin Matters in Shampoo

Biotin (Vitamin B7) is a water-soluble vitamin that supports keratin production, the protein forming hair structure. Unlike temporary volumizers, biotin shampoos work at the follicular level to strengthen strands from within, reducing breakage over time.

How Hair Strengthening Works

Effective shampoos combine biotin with proteins like collagen to create a protective layer around each strand. This dual action prevents split ends and minimizes damage from heat styling or environmental stressors.

Choosing the Right Shampoo

Look for sulfate-free formulas with biotin and natural oils. Sulfates strip natural oils, counteracting biotin's benefits. Pair with a lightweight conditioner to avoid weighing hair down.

Common Haircare Mistakes

Over-washing (more than 4x/week) can weaken hair. Use lukewarm water – hot water opens cuticles excessively, causing moisture loss. Always rinse biotin shampoo thoroughly to prevent residue buildup.

When to Expect Results

Consistent use for 6-8 weeks allows biotin to improve hair elasticity. Track progress by monitoring shed hairs during brushing – reduced breakage indicates effective strengthening.
