Products that claim to give you long, luscious locks seem to be flying off the shelves at the moment, but are they actually worth the hype? According to trichologist and founder of Root Cause Scalp Analysis Bridgette Hill, there's some important information to know before going full speed ahead on purchasing a product that's labeled as a hair growth serum.
"It's first important to clearly state that we identify serums and topicals as hair loss prevention products versus hair growth products," Hill shares. "There is no serum or active ingredient to date that is proven to grow hair. No product can regrow a dead hair follicle, meaning a hair follicle without a viable blood source. The FDA-approved topical drugs to treat androgenic or genetic hair fall address loss prevention, not hair growth."
With that distinction, Hill also wants to highlight the benefits of using a hair loss prevention serum and how strands become thinner in the first place. "What is being experienced with 'hair growth' serums is the reawakening of the hair follicle," says Hill. "It creates a healthier scalp microbiome, which increases the numbers of hair fibers that each follicle produces. To clarify, each hair follicle can produce multiple hair fibers and most people can have two to five hair fibers per hair follicle. (This is genetically predetermined.) As the follicle is compromised, the follicle produces fewer hair fibers, which results in 'hair loss' and thinning. The benefit and goal of these serums is to address miniaturization in its infancy stages for the best results."
Even if hair loss isn't a concern for you and you simply would love a serum to help promote long, luscious locks in some way, you can still look for hair strengthening serums containing ingredients that help keep breakage at bay. Hill recommends looking for hair products containing ingredients like saw palmetto, caffeine, licorice extract, pfaffia extract, ergothioneine, ginseng root, and burdock root. These will help nourish your hair at the root so strands have the opportunity to grow longer than ever before. Keep scrolling below for a few options recommended by Hill and other user favorites.
1. Groh Stimulating Scalp Serum
2. Dr. Barbara Sturm Scalp Serum
Hill also loves this formula from Dr. Barbara Sturm. Its key ingredients are hyaluronic acid and purslane, which provide an extra boost of hydration and restore the scalp's natural moisture balance. Purslane is also an ingredient that helps fight free radicals, which can potentially damage the hair follicle.
3. Virtue Flourish Nightly Intensive Hair Rejuvenation Treatment
Virtue's Flourish Nightly Intensive Hair Rejuvenation Treatment is another top pick of Hill's for its ability to help rebuild fragile locks. It contains a shampoo, conditioner, and density booster that strengthens hair and helps it appear thicker.
4. Act + Acre Cold Processed Stem Cell Serum
5. Vegamour Gro Hair Serum
6. René Furterer Triphasic Reactional Concentrated Serum
René Furterer's leave-in concentrate aids thinning hair by utilizing a powerful lotus mineral complex that helps balance the scalp. It also contains pfaffia extract, a star ingredient Hill says is key to look for when selecting a serum.
