Frequently Asked Questions

How long until I see results?

As a water-soluble B vitamin it can take time for biotin to build up as it constantly needs to be replenished by your body.

Taking supplements should always be a long-term plan and results will vary significantly from person to person as we're all unique on different.

On average it can take up to 3 months before there's a visible change in your hair, however some customers report noticing a change after just a few weeks.

We always recommend taking your daily dose of Puro Biotin Complex for a few months before assessing your results.

What makes this product better?

Our pure & potent formula not only contains 10,000μg of ultra high strength biotin (one of the strongest concentrations on the UK market) - it's also supported by 4 other hand-picked ingredients to support hair, skin & nails.

Plus unlike most supplements it's clean label & free from hidden nasties like synthetic additives, fillers & bulking agents - just 100% natural ingredients.

Is this vegan-friendly, gluten-free & cruelty-free?

Yes. This product is suitable for vegans and vegetarians and contains no gluten, wheat or dairy. It's also GMO-free and not tested on animals.

Can I take this with Collagen Complex?

Yes. This is an extremely popular combination with customers and we've received excellent feedback on this pairing. These two products have been expertly formulated to work together in partnership for superior effectiveness. Collagen is an excellent choice for skin health & anyone looking to boost their levels which naturally deplete from your mid-20s.

Is this product for both men & women?

Yes. This product is unisex and will offer the same benefits for men looking to support hair, skin & nails too. Around 30% of our customers for this product are male who have given some excellent feedback!

Can I take this during pregnancy?

While biotin deficiency is common during pregnancy, this is a high strength product formulated for beauty-related benefits and so we recommend consulting with your GP before taking this supplement.

    3 month’s in

    I got sent these as a complimentary so they were just gathering dust but over the last few years I’ve suffered with hair loss due to severe iron deficiency. After several infusions in 2024/25 my hair loss eased off. I started with the purolabs menocomplex which are amazing so when I got the biotin freebie I decided to give it a go. I’m in the hairdressers now as I write this & my hairdresser said she couldn’t believe how long and thick my hair is! So I’ve already signed up for the subscription so let’s see if it gets any better than this?

    I love for my fin eyebrows and nails

    Purolabs Biotin Complex has helped me feel calmer and less overwhelmed. It perfectly supports the nervous system.

    These vitamins also boost keratin production, nourishing my dull skin and damaged hair. I have always struggled with brittle nails, but now they seem to be getting stronger and growing faster, as is my hair too.

    I’ve also been concerned about my eyebrows and eyelashes, which always felt sparse and invisible, but now I can see that they're growing fuller. I believe that Purolabs Complex will help them look better.

    Even though it’s only been a month since I started taking these supplements, I truly believe they are making a positive impact on the keratin production, as well as supporting my hair and nail growth. They also seem to provide a comforting boost to my nervous system during stressful times. I’m excited to continue this journey to healthier skin, nails, and hair!

    Biotin Complex - Really easy to take

    Really easy to take, they are in capsule form and unlike other collagen supplements I have taken, there is no after taste.

    I’ve been taking these for 4 weeks and looking forward to seeing results with prolonged used.
