Since collagen protects the layer of skin that contains hair roots, it may help prevent age-related hair loss and thinning — but research on these effects is currently unavailable.
Collagen is one of the building blocks that help produce keratin, the protein that makes up the hair. The more collagen the body has access to, the easier it will be for it to start hair regrowth.
No direct, randomized clinical trials have shown sound evidence that collagen helps with hair loss. Most studies have been undertaken by companies that sell collagen supplements themselves. Therefore, most studies on collagen for hair loss have shown weak data or strong bias.
Collagen supplements take as minimal as two weeks to show visible improvements on your hair. Taking collagen supplements daily can make your hair softer, smoother, and shinier. It can also improve your hair texture, as well. It also reduces flaking and itching of the scalp.
If you're looking for the best treatment for thinning hair and maintaining your hair health, we strongly recommend biotin over collagen. It's far superior in terms of topical absorption and can be absorbed from many foods as part of a healthy, varied diet.
Collagen supplements may lead to mild side effects such as bloating, heartburn, and feelings of fullness. If you have food allergies, make sure to purchase supplements that don't contain your allergens.
“Both vitamin D deficiency, as well as vitamin D excess, may cause hair loss,” Chacon explains. A 2020 study in the International Journal of Dermatology found that vitamin D deficiency may also play a role in the development and severity of androgenetic alopecia, also known as male pattern baldness.
In short, no. While biotin has proven benefits for hair growth in people with biotin deficiencies, it doesn't have any effect on male pattern baldness. MPB is hormonal and genetic, and biotin, as a vitamin, simply isn't involved in the male balding process.
While biotin is added to some shampoos that claim to reduce hair loss, there is no evidence that this works. Consuming foods rich in healthy vitamins and minerals will help with overall hair health.
So the question is – Can too much collagen cause hair loss? The answer is no. If the person consumes the doctor prescribed amount of collagen, then there is no danger. Collagen can also be used externally, in which case the collagen can cause side-effect if the person is allergic to it.
Human collagen helps cells produce testosterone.
So which supports hair growth more: collagen or biotin? Based on scientific studies, it seems that collagen has a better claim to improving the condition of your hair. However, both can actually be used together for well-rounded nutrition and countless health benefits, aside from promoting hair regrowth.
Generally, for improved skin and hair health, 2.5-10 grams of collagen peptides can be taken orally for 8-12 weeks daily.
A 2019 review of clinical studies published in Nutrients found that taking 2.5 – 15 grams of hydrolysed collagen peptides each day is generally safe and effective.
1 Collagen may help in Hair loss
Collagen keeps both hair follicles supple and strong. Collagen can be used to replenish hair loss and make for stronger, more luscious locks and luckily for those looking to promote healthy hair growth there are plenty of collagen supplements on the market right now to do just that.
Collagen may promote healthy hair in a variety of ways. For one, your body may be able to use the amino acids in collagen to build hair proteins and strengthen the skin that contains your hair roots. It may also prevent hair follicle damage and graying.
It may seem strange, because even though DHT levels are raised, production is limited. Using zinc as a DHT blocker is not effective. Zinc helps to keep hormone levels regulated, which is one of the reasons why it is so effective in preventing and treating hair loss.
Biotin is also known as vitamin B-7. It forms fatty acids and glucose. It also helps metabolize carbohydrates and amino acids, and it aids in breaking down fat in your body. These functions make biotin an important part of creating the energy your body needs.
Symptoms of low B12 often occur when blood level drops below 300 ng/l and include hair loss, breathlessness, lack of energy palpitations, bleeding gums, mouth ulcers, tingling in the hands and feet. There are two types of B12 deficiency: Lack of dietary B12 – usually vegetarians and vegans.
But scientific research is scarce on how long it will take for hair to grow back — and if there is a significant amount of hair regrowth — after upping your vitamin D intake and improving your levels. Anecdotal evidence, though, suggests hair may stop shedding and regenerate in as little as two months after treatment.
Studies have shown that daily collagen supplements can help make your bones denser, slowing the aging process that makes them brittle and helping your body to produce new bone. Oral collagen supplements have been shown to improve skin hydration and elasticity for older people. They might also help to lessen wrinkles.
Turns out, newer studies have recently emerged indicating that consuming anywhere between 1,000-1,500mg of collagen per day may still be enough to get you glowing.
Collagen is generally considered to be a safe and nontoxic daily supplement for healthy individuals, and most people won't experience adverse side effects.
