How does collagen take care of hair? Here is the latest thing scientists have revealed

The use of collagen in hair care is part of the latest cosmetic trends that promise to enhance its vitality and shine. But is it just propaganda or does this ingredient really contribute to stronger and thicker hair growth?

Collagen is defined as a protein that the body produces to maintain the elasticity of the skin and scalp, but this protein is subject to a decrease in its natural levels as a result of stress and aging. This makes the skin more susceptible to dryness and exposes the hair to breakage and loss. Compensation for any deficiency in this protein depends on nutritional supplements and topical care.

Collagen does not grow new hair strands, but it helps create the ideal environment for them. Collagen can make a clear difference in the strength and density of hair, and it acts as an antioxidant that protects hair follicles from free radical damage that leads to accelerated gray hair and hair loss. Collagen also contributes to maintaining the elasticity of the scalp and stimulating its blood circulation, which enhances the delivery of nutrients to the hair roots. It strengthens the structure of weak hair, reduces its fragility and loss, and also nourishes the scalp, which contributes to enhancing hair softness and shine from the roots to the ends.

Collagen is available in two types: nutritional supplements and topical products. For the first type, it is recommended to choose hydrolyzed collagen peptides that are easily absorbed by the body, with the daily dose ranging between 5 and 10 grams, which are added to coffee, juice, or warm water. You can also choose nutritional supplements that contain collagen and vitamin C at the same time. Marine collagen is ideal for skin and scalp care, and as for topical products rich in collagen, the most notable are shampoos and masks that repair damaged hair. It is recommended to use it alongside nutritional supplements for double effectiveness.

The effectiveness of collagen begins to appear on the hair within a period of 8 to 12 weeks of use, as the hair texture becomes softer, its breakage decreases, and its shine increases. Some ingredients, in addition to collagen, work to improve hair condition, including:

• Biotin: which supports keratin production and strengthens hair. When combined with collagen, it helps improve hair structure and reduce hair breakage more effectively than using either of them alone.
• Keratin: It is the basic structural protein of hair. Keratin treatments or formulations help repair damaged hair fibers while collagen provides essential amino acids that support keratin formation. This makes the two a beneficial combination for strengthening hair and enhancing its elasticity.
• Peptides: These are small protein molecules that stimulate the activity of hair follicles and enhance collagen production in the scalp. It works with collagen to improve scalp health and promote hair growth.

How to support these findings
Some habits contribute to supporting natural collagen production in the body, including:
• Eat foods rich in protein, such as eggs, fish, chicken, and legumes, as they enhance collagen production.
• Obtain sufficient vitamin C for the body by eating fruits and vegetables rich in it, such as: citrus fruits, kiwi, and sweet peppers.
• Maintain hydration by drinking enough water to maintain scalp elasticity.
• Get enough sleep because collagen production reaches its peak during deep sleep cycles.
• Limit your intake of sugar and processed foods that contribute to accelerating the breakdown of collagen.
Protecting hair from the heat of electric styling tools and UV damage.
