Anagain is a trademarked ingredient derived from pea sprouts and used in some hair loss products to promote growth and reduce shedding. Here is a closer look at what it is, how it works, the evidence, and where it fits.

What Is Anagain?

Anagain is a patented ingredient from organic pea sprouts (Pisum sativum), developed by Mibelle Biochemistry. It is said to reactivate hair follicles and support healthy growth by signalling trichogenic factors in the dermal papilla cells.

How It Works

According to the manufacturer, Anagain rebalances the ratio of anagen (growth) to telogen (resting) follicles by stimulating the dermal papilla cells and extending the anagen phase of the hair growth cycle.

The Evidence

Mibelle ran a clinical study of 20 women with hair thinning; after 3 months, participants reportedly saw a 78% increase in the anagen-to-telogen ratio. The limitations matter: a small sample of 20, a study run by the ingredient manufacturer, and no independent peer-reviewed trials.

Potential Benefits

On the available evidence, Anagain may stimulate follicle activity, raise the share of hairs in the growth phase, and lower the share in the resting phase. It may help most with telogen effluvium (stress-related shedding) or early alopecia.

How to Use

Follow the product instructions. For shampoos, massage into the scalp and leave on for 2-3 minutes before rinsing; for serums, apply to the scalp and massage gently. Use consistently for at least 3 months.

Realistic Expectations

Keep expectations realistic: results vary, it is likely most effective for mild to moderate thinning, and it works best as part of a complete anti hair fall routine.

The Bottom Line

Anagain is a promising, plant-based option for hair thinning. Early results are encouraging, though more independent research is needed. As part of a consistent routine, products with Anagain may help those experiencing thinning.
