FAQs

Hair Growth Serums aim to stimulate hair growth at the root by supplying a range of active ingredients to the scalp and invigorating hair follicles, reducing hair loss and resulting in a thicker and fuller head of hair. To learn more about how hair growth serums work head to our article here.

To use a hair serum for scalp and hair health, apply one to two pipettes directly onto a clean, dry scalp. Gently massage the serum in to help it absorb, and do not wash your hair or scalp after application. For best results, use once daily as part of your routine. If applying to a specific concern area, use one to four smaller drops depending on the size of the area, helping support a healthier-looking scalp and stronger-looking hair over time.For more in-depth information on how to apply hair growth serum, head to our article here.

Yes, Anagain is a plant-based active ingredient used in hair care to support hair growth and density. It’s derived from organic pea sprouts and is designed to help improve the appearance of hair by encouraging thicker, fuller-looking strands over time.Often used in an Anagain hair growth serum, such as the UKHAIR Hair Growth Serum, this ingredient works by supporting the hair’s natural growth process, helping hair look stronger, denser and healthier with consistent use. Anagain for hair growth is valued for its ability to improve overall hair vitality, making it a popular choice for those looking to address thinning and support long-term hair health.

We recommend allowing around 12 to 18 weeks to see results from a hair growth serum, as scalp hair grows more slowly than eyelashes and eyebrows. The hair growth cycle takes time, so consistent daily use is key, giving your scalp and hair follicles the chance to absorb the active ingredients and support the appearance of longer, stronger and healthier-looking hair over time.

Results from a hair growth serum are not permanent without continued use, as hair growth follows a natural cycle. A hair serum works by supporting healthier-looking, stronger hair while it’s used consistently, but if you stop applying it, your hair will gradually return to its natural growth pattern over time.For long-term results, ongoing use is recommended to help maintain the appearance of fuller, thicker and healthier hair. Consistency allows the active ingredients to continue supporting hair health, making a hair serum an effective part of a long-term hair care routine rather than a one-time solution.

    Love this product

    After a traumatic event with significant blood loss + two emergency surgeries, I lost SO MUCH hair. I’ve been a huge fan of the lash serum for years as my lashes have always been so short and this serum is also a huge game changer.

    I decided to try the hair serum and I’m blown away with how amazing this is working. Photo of my hair before (natural state, first photo)

    As well as following the major event (2nd & 3rd photo), and currently (three months of using the serum)

    Hair growth after chemo

    I got the serum to help with hair growth after having chemo. I started using it when my hair resembled a very short buzz cut and have used it consistently for over 2 months and definitely seeing results! It’s growing well and it really helps with the condition of my hair, also love that it doesn’t leave a greasy film on my hair!
