Worldwide cult eyelash and eyebrow brand RapidLash soon followed their revolutionary eyelash enhancing product with a version for brows. The best part? It’s available in high street drugstores at a very reasonable price, and it WORKS.

What Are the Results?

Users report that it’s easy to use and showed a noticeable difference in their brows as soon as 3 weeks after beginning use (although the brand advise that full effects are usually achieved within 60 days). The small mascara-type wand makes it easy to work the product into the brows and get a precise application so as not to waste any product. As with most other serums, it’s recommended that you use this product twice a day – once before makeup in the morning, and once at night after your skincare routine.

Ingredients & Formula

RapidBrow eyebrow serum contains a host of must-have ingredients for hair regrowth. Polypeptides encourage hair renewal and growth, while biotin contains several vitamins and minerals to strengthen your new hairs. Keratin is a strengthening and conditioning agent, as well as sweet almond extract. These natural ingredients ensure customers can be confident they’re not using harsh chemicals on their skin, and that their newly grown hairs will be strong and full.

The omission of prostaglandin analogues in this product varies as a pro or a con between customers. This is the ingredient contained in some other serums that darkens hairs. Customers with fair hair who simply want to grow and enhance their natural brows without changing the hair’s color will be pleased that this formula doesn’t contain the ingredient. Customers wishing for darker brows won’t find that with this product, but could obviously use makeup or another brow coloring product as well. For the low price of RapidBrow, you could treat yourself to a new eyebrow pomade to go with it!

Budget-Friendly Serum

Overall, if you’re thinking of trying out a new product to enhance sparse and thinning brows, you can’t go wrong with trying RapidBrow. It’s reasonably-priced, contains natural ingredients, and shows real results in record time. If you don’t have the budget for some of the more expensive formulas, RapidBrow is a strong competitor to luxury branded serums.

RapidLash: The Brand Story

Although quite a young company, the company behind RapidBrow, RapidLash, are quite the success story – and that’s because of the quality of their products.

Here we break down everything you need to know about RapidLash, and why they are the go-to brand for eyebrow and eyelash regrowth.

An Award-Winning Product

Both the RapidLash Eyelash Serum and the RapidBrow Eyebrow Enhancing Serum have won awards for the high quality of their product, and when you use it, it shows.

Amazon have given RapidLash their stamp of approval, which is quite the accolade. In the UK, Amazon tag them as their choice of the best eyebrow serum – very high praise from one of the world’s biggest companies.

A Family Business That Cares

The founding story of this business is super cute. Despite being a globally successful company, they still like to describe themselves as a ‘mom and pop shop’. The founders, Robert and Carol, are married, and their commitment to making products that are kind for women really shows their family ethics in action.


Long before the creation of RapidLash, Robert was already quite the name in the cosmetics business. He’s long been recognised as advancing the field of science of professional and medical skincare, and his expertise proved invaluable when founding the business in 2008.

One of his advancements changed the make-up industry forever. When you purchase RapidLash, you know you’re buying a little part of makeup history. When launched in 2008, RapidLash was the first product specifically marketed for that purpose ever. Now, the industry has been revolutionised. Look how far we’ve come.

Dermatologically Approved

All RapidLash products are tested by dermatologists and proven by clinicians. The company take the utmost concern in making sure their products are great for skin and hair before they go on the market.

They even consult ophthalmologists (specialised eye-doctors) to test all their products first, so you can be confident that it’s not only great for skin, but entirely safe for your eyes as well.


RapidLash don’t use any parabens in their serums, which may not sound like a big deal, but parabens are in around 85% of cosmetics in the US, including toothpastes and hand wash. And they’re pretty concerning. Parabens have an estrogenic increasing effect that’s been linked to cancers, and environmental damage – yikes.

Instead, RapidLash use the natural Pumpkin Seed and Soybean oil to make a kind product, and enrich it with Vitamins which have restorative properties. Great ingredients that produce great results.

Consumers Love It

Most people who go for RapidLash don’t look back. Their focus on making such a safe product means bad reactions to the formula are kept to a minimum (of course, this depends on your skin type and if you suffer from reactions to allergens – always check the ingredients). Consumers who use the product become converts due to its winning formula and bargain price. Lashes go from short and sparse to long and lovely, and eyebrows go from sad and small to brows that’d make Brooke Shields proud!

RapidLash Give Back

You can enjoy buying a RapidLash product like RapidBrow enhancing serum guilt-free. Every year they donate a portion of their profits toward breast cancer organisations, so that sufferers have great infrastructures to support them, if the worst should happen. This is a product that works, with an added good deed when you buy it!

Our Verdict

Besides its proven capability to regrow and enhance your brows, it boasts several other winning points: it’s not tested on animals, it’s paraben-free, fragrance-free to reduce irritation, and is totally safe for use with contact lenses. It retails for $50 (about £37 for British buyers), which is much more budget-friendly than most other leading eyebrow regrowth products.
