Biotin’s Benefits

Also known as vitamin B7 (or vitamin H), biotin is a water-soluble vitamin which naturally supports hair growth by helping to create amino acids and promoting production of keratin (the main component of hair). Biotin is believed to strengthen existing strands, as well as nourish growing hair follicles, improving thickness and durability.

Thinning hair and hair loss are common symptoms of biotin deficiency. While biotin has proven benefits for hair gross in people with biotin deficiencies, it is not proven to have any effect on healthy people.
Pregnant women are particularly subject to low biotin levels and biotin deficiencies

Biotin exists in edible form, like vitamin supplements. However, if taken excessively, they are not always safe. Instead of eating biotin like candies, you may want to add it to your hair cleansing routine with a natural and vegan biotin shampoo!

Best Cruelty-Free & Vegan Biotin Shampoos for Hair Growth

Whether you’re looking for a biotin hair product or any hair growth product in general, always go for the most natural solutions. Why? If you want to stop your hair from falling, you don’t want to develop another problem! Some biotin-based shampoos contain chemicals which are linked with different types of irritations, allergies, hormonal dysfunctions and even cancers.

Safe, natural & cruelty-free shampoos often include essential oils and other natural active ingredients which together help biotin’s absorption into the scalp and nourish hair follicles. To save you time, we picked for you some of the best cruelty-free, vegan and natural biotin shampoos.
