Alright, let’s talk hair growth. If you’ve been down the rabbit hole of hair care trends, you’ve probably heard about hypochlorous acid (HOCl). Some people swear by it for scalp health, but does it actually help your hair grow? Let’s break it down in real talk.

What Even Is Hypochlorous Acid?
No fancy science lesson here—hypochlorous acid is something your body already makes to fight off bacteria and inflammation. It’s been used forever in wound healing and skincare because it’s gentle but super effective. Now, people are using it on their scalps, hoping for better hair growth.
So…Will It Actually Make Your Hair Grow?
Here’s the deal—hypochlorous acid won’t magically sprout new hair, but it does help create the perfect environment for healthy growth. Think of it like prepping your garden soil before planting flowers. A clean, balanced scalp means:
✔️ Less inflammation and itchiness (because an irritated scalp isn’t a happy one)
✔️ No harmful bacteria or fungi messing with your hair follicles
✔️ A well-balanced scalp microbiome
✔️ Faster healing, which could help follicles work better
So while this stuff won’t give you instant Rapunzel vibes, it might just help set the stage for stronger, healthier hair over time.
What Actually Works for Hair Growth?
If you’re serious about growing your hair, hypochlorous acid is just one piece of the puzzle. Here are some products that have actual science behind them:
Minoxidil (Rogaine®): This one’s FDA-approved and proven to help with hair regrowth.
Nutrafol®: A solid supplement with vitamins and plant-based ingredients that support hair health.
Olaplex No. 3 Hair Perfector: Not for growth, but great for keeping your hair strong and preventing breakage.
The Ordinary Multi-Peptide Serum: A budget-friendly serum packed with peptides to help thicken hair over time.
Bottom line? No single product is a miracle fix—but combining a few good ones and staying consistent can make a huge difference.
