Wondering what biotin actually does for hair, and how much of it you need? Here we go through what biotin is, what the authorised claim covers, how much sits in a daily dose of Hair Luxious, and how a supplement fits into a daily routine.
What is biotin?
Biotin, also known as vitamin B7, is a water-soluble vitamin involved in the body's normal cell metabolism. It is one of only a small number of nutrients with an authorised hair claim in the EU: biotin contributes to the maintenance of normal hair. Biotin also contributes to the maintenance of normal skin and to normal energy-yielding metabolism.
Hair Luxious hair vitamins, such as Premium hair vitamins for women, contain 2500 µg of biotin per daily dose, alongside zinc and selenium. Zinc contributes to the maintenance of normal hair, skin and nails, and selenium contributes to the maintenance of normal hair and nails.

How much biotin do you need?
The EU nutrient reference value (NRV) for biotin is 50 µg per day. Biotin is found in foods such as eggs, nuts, seeds, oily fish, liver and wholegrains, and a varied diet normally supplies it. Deficiency is uncommon.
Hair supplements typically contain considerably more than the reference value. Hair Luxious contains 2500 µg per daily dose. Biotin is water-soluble, so the body does not store a surplus in the way it does with fat-soluble vitamins.
One thing worth telling your doctor
High-dose biotin can interfere with certain laboratory blood tests, including some thyroid and cardiac tests, and skew the result. This is well documented and easy to work around: mention that you take a biotin supplement before giving a blood sample, and follow whatever your doctor advises about pausing it beforehand.
As with any supplement, speak to a healthcare professional first if you are pregnant or breastfeeding, take prescription medication, or have an underlying health condition.
Fitting it into a daily routine
A food supplement is designed to be taken consistently as part of your normal diet, so the practical question is usually which format you will actually remember. Hair Luxious Premium hair vitamins come as tablets and as gummies in elderberry and strawberry flavour. Take them with a meal, at the same point in the day, and the routine tends to look after itself.
Alongside the supplement, the ordinary things still matter:
- A varied diet with protein, fruit and vegetables
- Enough water through the day
- Going easy on heat tools and chemical treatments
- A mild shampoo and conditioner suited to your hair type
Food supplements are not a substitute for a varied and balanced diet and a healthy lifestyle. Do not exceed the stated daily dose.
