What does vitamins do for hair or whats is important vitamins for hair including their prosity
Vitamins are essential for healthy hair because they support key processes in the hair growth cycle and maintain the structure, strength, and hydration of the hair strands. Here's a breakdown of why vitamins matter for your hair, especially in relation to hair porosity (how well hair absorbs and retains moisture):
1. Support Healthy Hair Growth
Vitamins like biotin (B7), vitamin D, and vitamin A help regulate cell growth, including the cells in your hair follicles. Without them, hair can become weak, brittle, or stop growing.
2. Strengthen Hair Shaft
Vitamins such as C and E act as antioxidants, protecting hair follicles from oxidative stress and strengthening the hair shaft, which is especially important for high porosity hair prone to breakage.
3. Improve Scalp Health
A healthy scalp is the foundation for healthy hair. Vitamin D, B-complex, and zinc help reduce inflammation and support sebum (natural oil) production, improving hydration and preventing flakiness or hair loss.
4. Affect Hair Porosity
Porosity is about your hair’s ability to absorb and retain moisture, often influenced by genetics, chemical treatments, or damage. Vitamins support:
Low porosity hair (resists moisture): Needs help with vitamin C for collagen synthesis and iron absorption to improve nutrient flow to follicles.
High porosity hair (absorbs but loses moisture quickly): Needs vitamin E, biotin, and protein-building B vitamins to repair and strengthen the cuticle layer.
Key Vitamins for Hair (and Porosity)
Vitamin Role in Hair Health Effect on Porosity
Biotin (B7) Supports keratin production Helps with breakage in high porosity hair
Vitamin A Helps skin glands make sebum Keeps low-porosity hair moisturized
Vitamin C Collagen production & iron absorption Strengthens hair cuticle, improves elasticity
Vitamin D Supports follicle cycling Prevents thinning and fragility
Vitamin E Antioxidant, improves circulation Protects porous hair from damage
B-complex (B1, B2, B3, B5, B6, B12) Energy for follicle cells Improves moisture retention and hair strength
- Minerals can also take place
Iron – prevents hair shedding
Zinc – regulates oil production and tissue repair
Magnesium – reduces scalp inflammation
