Insufficient evidence — aloe vera can soothe the scalp and may help with dandruff and itch, but there is no good evidence that it regrows hair or stops pattern hair loss.
Aloe vera is a gel from the leaf of the aloe plant, used in many shampoos, conditioners, and scalp products for its moisturizing and calming feel. Its best-supported use is as a soothing topical: it can reduce dryness, itch, and flaking, and some evidence suggests it may help with seborrheic dermatitis (a common cause of dandruff). A healthier, less irritated scalp can make existing hair look and feel better and may reduce scratching-related breakage. However, none of this means aloe vera treats the biological causes of hair loss. There are no reliable human trials showing it reverses androgenetic alopecia (male or female pattern hair loss) or meaningfully increases hair density.
Most claims that aloe "regrows hair" come from lab or animal studies, marketing, or anecdote rather than well-designed clinical trials, so they should be treated with caution. Aloe is generally well tolerated, though some people develop contact allergy or irritation, so patch-test a new product first. It is reasonable to use an aloe-containing product if you like how it feels on your scalp or it helps with dandruff and itch. The bottom line: treat aloe vera as scalp comfort and cosmetic care, not a hair-loss treatment — if you want to actually slow shedding or regrow hair, use a proven option like minoxidil or finasteride and see a clinician to confirm the cause of your hair loss.

FAQ
Can aloe vera regrow hair?
There is no solid clinical evidence that aloe vera regrows hair or increases hair density in people. It can soothe and moisturize the scalp and may help dandruff, but that is a comfort and cosmetic benefit, not regrowth. For actual regrowth, treatments like minoxidil have far stronger evidence.
Is it safe to put aloe vera on my scalp?
For most people aloe vera is gentle and well tolerated on the scalp. A small number of people develop irritation or an allergic reaction, so apply a little to a small area first and watch for redness or itch over a day. If you notice sudden patchy hair loss, severe scaling, or scalp pain, see a doctor rather than relying on aloe.
