While advertising states that the hair is our crown, and it must be full and voluminous, we’re ready to buy and try dozens of products, even if we’re not familiar with their ingredients. One good example is biotin. What is it? Does it really help hair to grow? Get ready to find out the truth.

What is biotin? 

Also known as vitamin H, or B-7, biotin is a water-soluble vitamin, part of the vitamin B family. Thanks to the biotin in our bodies, certain nutrients are converted into energy, and it’s also essential to keep hair, skin, and nails healthy. 

How biotin deficiency results and acts in the body

Frankly, biotin deficiency occurs rarely. That’s because many foods naturally produce large amounts of this vitamin. In general, pregnant women and people who drink high amounts of alcohol have more chances to develop it. Also, if you eat raw eggs regularly, it’s more likely you’ll face a biotin deficiency. The reason is the protein avidin, found in raw egg whites, which binds to biotin, preventing your body from absorbing it.

But when it happens, biotin deficiency is characterized by hair loss, dermatitis, vision issues, and even mild depression

This study intended to determine the significance of biotin deficiency in women complaining of hair loss. Of 466 women (aged between 9 – 92 years), biotin deficiency was found in 38% of women accusing hair loss. What outcome emerges out of this? That biotin can stop hair loss, but only if it’s generated by biotin deficiency.

Does biotin stimulate hair growth?

Despite the limited research to support biotin’s utility, it still gained fame for its claimed benefits on healthy hair growth. One study published in 2017 claimed that in all 18 cases of biotin supplementation use for thinning hair, the results showed an improvement.

Over the past decade, biotin’s popularity hugely increased, and you can now find more and more hair products with biotin. Have a peek at the data from Google Trends; twice as many people are searching for biotin information as in 2004.

A lot of manufacturers indeed add biotin into their formulations, such as shampoos and conditioners. But are they useful? Shortly, no. Remember that biotin is a water-soluble vitamin that needs to be taken orally to be effective. On the other hand, in serums, which are more active, biotin may improve the hair’s health and boost its volume. Still, biotin supplementation definitely helps women with thinning hair speed up and increase the hair growth rate.

While there’s nothing wrong with adding biotin products to your hair care routine, I can’t say it’s going to stop or slow down the hair loss. You’d need some medical-grade compounds, such as finasteride and minoxidil.


As discussed, it’s not bad supplementing your body with biotin. Since this vitamin has real benefits for hair growth, it’s worth taking. However, don’t expect to reverse hair loss (unless you face a biotin deficiency) or anything like that, but only to improve your hair’s health and make it look a bit better! 

Alternative treatments for hair loss

Many people know about biotin, but very few are aware of low-level laser therapy (LLLT). Do you know that lasers can make your hair grow faster and stronger? Yes, that’s exactly what LLLT does. It uses the energy emitted by low-level lasers to heat up the scalp and stimulate hair follicles to produce healthier hair. Don’t worry, the process is entirely pain-free and can be done at home via a laser hair growth device. Want to find more about LLLT? Check it here.

Redensyl is another excellent alternative for hair loss treatment. It’s an ingredient commonly found in anti-hair loss products, proven to reactivate hair follicles and move them from the resting phase to the growing phase. You definitely have to try these Redensyl products.
