“Using an eyelash serum can help to strengthen your natural lashes, keeping them long and strong and primed for growth ”

“Use deep conditioner often and a shampoo with Piroctone Olamine to protect against dry scalp and hair loss.”

Dr. Pyal, GP and Dermatologist
An eyelash serum is a specially formulated treatment designed to lengthen, thicken and nourish your natural eyelashes. Providing a kinder alternative to eyelash extensions, they typically contain a blend of ingredients to stimulate lash growth.
Eyelash Serums deliver active ingredients to the roots and lengths of the lashes to create the perfect environment for growth and to nourish and condition the lashes that are already there, prolonging the amount of time they stay attached and in turn creating the appearance of longer and fuller lashes. Head to our article ‘How Do Eyelash Serums Work’ to learn more.
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.
In short, eyelash serums are safe to use and are typically backed by rigorous testing and stringent quality control measures. As with all beauty products, different serums can affect people differently, which is why we always encourage patch-testing prior to using the product and ask that you consult your doctor before use if you suffer from any preexisting conditions.
This will depend on what point your lashes are in their cycle when you start to use the product. Some see longer lashes in as little as 25 days, but 12 weeks is when you should expect to see full results. Read more about lash cycles here.

I work at UKLASH and gifted this product to my grandma for Christmas — here’s her experience!
*Usage: She applied it mostly to the edges (not the whole scalp) every night. The 50ml bottle lasted about two months, though she initially used it incorrectly for almost a week (it’s 1-4 drops, not full pipettes, grandma! 😅), which made it run out faster.
*Results: This was the first hair serum she had ever used, so she couldn’t compare it to similar products, but she was thrilled with the results. She noticed plenty of new baby hairs growing along the edges as you can see in the 2nd picture below (the first image shows her hair before). Since she wanted to continue, I set up a subscription to make things easier for her and added the hair vitamins too.
