Peppermint essential oil
This can help promote hair growth during the anagen (or growing) phase. One study found that peppermint oil, when used on mice, increased the number of follicles, follicle depth, and overall hair growth.
A major active compound found in peppermint oil, menthol helps keep hair follicles active and stops them from shrinking. Peppermint oil contains 40% menthol. A study showed that peppermint oil is much better than minoxidil in preventing hair follicles from shrinking and activating dormant hair follicles.
The topical application of peppermint oil has been shown to increase the number and the depth of hair follicles. After 4 weeks, Peppermint Oil improved the hair growth by 92% compared with 55% of Minoxidil. It serves as an indicator for the efficacy of peppermint oil in the treatment of hair loss.
Truly dead hair follicles are almost impossible to reactivate, except with the help of medical/surgical treatment, so it's important that you take action on your dying hair follicles as soon as you're able – the earlier the better.
Apply peppermint oil directly to your scalp.
To apply peppermint oil directly, mix one to two drops into a tablespoon of jojoba oil, coconut oil or shea butter oil, then massage the oil into your scalp before washing your hair with shampoo.
In addition to kickstarting your follicles through targeted scalp massages, certain topical hair-care products like serums and scalp cleansers can help prompt your follicles to get back to work. They contain ingredients that, when applied directly to your scalp, work to stimulate and nourish your follicles.
Heat causes sweat. Both can cause clogged hair follicles and make them worse. Keep your body temperature down by drinking plenty of water and staying indoors when you can. If certain bacteria get into your hair follicles, it can clog them.

A histological analysis determined that the peppermint essential oil group had more significant increases in dermal thickness, hair follicle number, and hair follicle depth than the other groups – even more so than the minoxidil group.
As noted earlier, peppermint oil can repel lice (which can cause hair loss) and block 5a-reductase to minimize DHT in the bloodstream. Based on one safety report (3), the menthol constituent can also improve the penetration of other chemicals, a third property that may help with hair loss conditions.
While there are a few essential oils that can help to stimulate hair growth, Henry said that rosemary oil tends to be a top choice.
Please note: Undiluted peppermint essential oil can be toxic. It can cause burning and tingling on the scalp, and must never be used on its own.
Peppermint essential oil is so potent that undiluted it will cause your skin to tingle or burn.
"ACV unblocks follicles in the scalp so that strands have freedom to thrive," Ruggeri says. (Note: If you do use dry shampoo, Ruggeri advises spraying it on the mid-lengths of hair, rather than the roots, to prevent clogging the follicle).
If you damage your hair follicles after an injury, they can repair themselves and your hair will grow back. It could take up to four years before you see new hair growth out of damaged hair follicles, depending on the severity of your injury.
Essential oils such as lavender, peppermint, rosemary, cedarwood, lemongrass, thyme, clary sage, tea tree, ylang ylang and horsetail plant oil have already been proven in various degrees to improve hair regrowth and slow down hair loss.
One of the most widely used and proven treatments is minoxidil (Rogaine and various generic products). It's available in liquid, foam, or shampoo options. Stronger forms of minoxidil are also available by prescription. Minoxidil may cause side effects like skin irritation or unwanted hair growth on skin near the scalp.

Results showed that rosemary essential oil was just as effective a minoxidil. During the process, it helped the side effect of itchy scalp more successfully than minoxidil. Another study of rosemary leaf extract (different from the essential oil) showed it stimulated hair growth.
