Hair vitamins are supplements that are often advertised to improve hair growth, shine, thickness, and strength. They typically contain nutrients such as biotin, vitamins C and E, collagen, folic acid, and omega-3 fatty acids, as well as additional ingredients like ashwagandha and ginseng. However, according to an article from Healthline, there is little evidence to support the effectiveness of hair vitamins, and some supplements may even worsen hair loss or cause nutrient toxicity
. It is suggested that for most healthy people, hair vitamins are unnecessary, and instead, the focus should be on eating a nutritious diet, managing stress levels, exercising regularly, and getting enough sleep. One example of a hair vitamin product is HAIRtamin Vegan Hair Vitamins, which are advertised to support healthy hair, skin, and nails, and may reduce hair loss and thinning. The product contains quality ingredients and is gluten-free and cruelty-free
. Another example is Divi's Hair Vitamins, which are crafted with a blend of ingredients including Lustriva® and Divi's Roots-9 Complex to support hair from root to end. The product contains ingredients such as KSM-66® Ashwagandha Root Extract, Rhodiola Root Extract, and L-theanine, which are said to support healthy stress management and hair growth
. Additionally, Hair Volume™ tablets by New Nordic contain high amounts of biotin, pantothenic acid, zinc, copper, millet, horsetail, and apple extract, which are claimed to nourish the hair from within
. It is important to note that the effectiveness of these products may vary from person to person, and it is recommended to consult a healthcare professional if there are underlying issues with hair health.
