Quick Read on Why Antioxidants are Crucial for Healthy Hair
If you've been on social media in the last few years, you've seen the rise (and fall) of many popular ingredients in skincare and haircare. Yesterday's favorite may be old news today, so it can be difficult to pinpoint which ingredients remain must-haves when restocking your routine.
When it comes to tried and true ingredients that always deserve a place on your shelf, experts agree that antioxidants are beneficial for both skin and hair. With many pros, and few (if any) cons, "all hair types can likely benefit from the use of antioxidant haircare," board-certified dermatologist Brendan Camp, MD, says.

Benefits of Antioxidants for Hair
Experts agree that the benefits of antioxidants for hair run deep (into the scalp). Given that antioxidants boost both skin and hair health, their benefits can be seen from root to tip. "There are many reasons consumers should be using antioxidants in their hair care routines," says Reavey.
"Most importantly, they are a key ingredient in having healthy hair follicles which leads to stronger and thicker hair," Reavey continues. "Similar to how antioxidants in our diet boost our immune system, using antioxidant-rich hair care products helps to boost the circulation in our hair follicles and feed our scalp nutrients so that the follicles don’t weaken over time, promoting healthy hair growth."
Improve hair growth:
The experts all note that antioxidants can help improve hair growth by boosting blood circulation and nutrient supply to the scalp, which in return encourages hair growth. In a 2021 study conducted by the Society of Cosmetic Scientists, results showed that when adding antioxidants to shampoo and conditioner, a group of subjects with thinning hair saw less shedding and more fullness, concluding that antioxidants were in fact successful in helping hair growth and retention.
Protect hair follicles:
Antioxidants are protective ingredients. "They neutralize free oxygen radicals, which are unstable oxygen molecules that develop as a result of the body’s normal metabolism, and exposure to ultraviolet (UV) radiation and environmental pollution," Camp explains. "Free radicals can damage cellular structures such as DNA, lipids, and proteins."
Help reduce frizz:
The effects of free radicals as mentioned above by Camp can also translate to dry, frizzy, brittle hair. Antioxidants help prevent these issues.
Help prevent premature gray hair: "Antioxidants prevent the breakdown of melanin in the cortex of the hair strand which helps improve color retention and the integrity of hair," notes Friese. "Which means strong and healthy hair with possibly less graying."
Relieve dandruff:
Antioxidants can help with a variety of conditions including dandruff. Salicylic acid specifically works to dissolve dandruff and relieve the scalp.
