Biotin, also known as vitamin B7, is a cofactor for enzymes involved in fatty acid synthesis and amino acid metabolism. It supports keratin production, which forms the structural basis of hair strands.

Iron is essential for transporting oxygen to hair follicles. Adequate iron ensures proper follicle metabolism, which is necessary for healthy hair growth and strength.

Biotin or iron deficiencies may manifest as hair thinning, brittle strands, or slow growth. However, hair loss can also result from genetics, hormonal changes, or other health factors.

Biotin-rich foods include eggs, nuts, seeds, and legumes. Consistent intake supports keratin synthesis and overall hair quality.

Iron is abundant in lean meats, leafy greens, legumes, and fortified grains. Pairing iron-rich foods with vitamin C sources improves absorption.

While nutrients support internal hair strength, external care like gentle washing, protective styling, and minimizing chemical stress helps maintain hair resilience.

Can biotin supplements thicken hair?
Biotin supports keratin synthesis, but supplementation only benefits those with low biotin intake or deficiency.

How do I know if I need more iron for hair?
Hair thinning, fatigue, or pale nails may indicate low iron; blood tests can confirm deficiency before supplementation.

Biotin and iron are foundational nutrients for hair strength and resilience. Including these nutrients in your diet, alongside proper hair care, supports healthy follicles and stronger hair.
