The 14 Best Hair Growth Serums for Thicker Hair in Days
The 14 Best Hair Growth Serums for Thicker Hair in Days
Whether the cause is postpartum, aging, nutrition, stress, or some combination thereof, hair thinning and hair loss are fairly common concerns. And in a post-COVID world, they have only become more of an issue; research has found that those who've had a COVID infection are four times more likely to develop hair loss than those who haven't.
All this to say, products targeted to hair growth are more popular than ever. Scalp care, in particular is having a moment, with Ayurveda-inspired scalp oils spiking in popularity. Pinterest even named scalp care one of their biggest predicted trends for 2023. And although previously minoxidil-based products like Rogaine were the only viable options for thinning hair, hair growth serums are now gaining popularity.
"There's limited data on hair growth serums for thinning hair compared to FDA-approved minoxidil, but some preliminary data are very hopeful," Minnesota-based dermatologist, Jenny Liu, says. Ahead, we gathered 14 of the best hair growth serums on the market, including picks from Liu as well as celebrity hairstylist Clariss Rubenstein.
