Biotin, collagen, iron, vitamin D, saw palmetto, keratin, and omega-3s are among the supplements that claim to boost hair development and offer users fuller, thicker hair, but do they work?

Are Hair Growth Vitamins Effective?

The evidence on whether hair growth supplements help varies each supplement, and further research is needed in most cases. The following are some examples of popular hair-growth supplements:

Collagen

Collagen is a naturally occurring protein that can make aged skin seem younger by reducing wrinkles.

Collagen levels in hair follicles were found to be high in a research published in the Journal of Investigative Dermatology, suggesting that the protein is vital for hair health.

Collagen has to be studied more to see whether it might assist with hair loss.

Bone broth, spirulina, fish, eggs, and gelatin are all good sources of collagen.

Iron

Hair loss is frequently caused by iron deficiency, especially in women.

Iron supplements may aid hair regeneration if hair loss is caused by an iron deficit.

Lean meat, shellfish, poultry, iron-fortified morning cereals and bread, white beans, lentils, spinach, kidney beans, peas, almonds, and some dried fruits, such as raisins, are all good sources of iron.

Palmetto (Saw Palmetto)

The saw palmetto is a shrubby palm found in the southeastern United States.

It has been tried to cure hair loss, although there is little evidence of its efficacy.

In one research, males who were given topical saw palmetto and trichogen veg complex had more hair.

Saw palmetto may aid in hair growth, but additional research is needed.

Keratin

Hair, skin, and nails all contain the protein keratin.

Although the body manufactures keratin, some suggestions supplementing with it can help make hair fuller, stronger, and shinier.

There have been no studies that demonstrate that keratin aids hair development.

Supplementing with keratin may potentially be detrimental.

Omega-3s

Omega-3 fatty acids are important fatty acids that nourish hair.

Omega-3s have been found in test tubes and animal studies to help decrease hair loss and even boost hair growth.

Human studies are required.

Fish and other seafood (particularly cold-water fatty fish like salmon, mackerel, tuna, herring, and sardines), nuts and seeds (including flaxseed, chia seeds, and walnuts), plant oils (such flaxseed oil, soybean oil, and canola oil), and fortified foods are all good sources of omega-3s (such as certain brands of eggs, yogurt, juices, milk, soy beverages, and infant formulas)
