Hair Gain Now is a British hair care company that makes vegan supplements and topical treatments, all built on scientific formulation, for people dealing with excess shedding who want thicker hair. Its headline ingredient is AnaGain, taken from organic pea shoots, which is said to work by triggering signalling molecules in the hair follicles. Formulas are put together without artificial additives, with the idea of nourishing hair from the inside, and the range also covers scalp health and general hair vitality.
The best known item in the line-up is the award-winning Hair Gain Pampering Gift Set, which pairs a nourishing hair mask with a biodegradable wide-tooth comb and a bow headband, packed in a soft sage cosmetic case. Alongside it the brand sells topicals, gummies and accessories, so a routine can be built from several products at once.
Payment is straightforward: shoppers can use Google Pay, Apple Pay, PayPal, Klarna, Clearpay or Shop Pay at checkout. Standard shipping is free once an order passes £50, and every monthly subscription plan comes with delivery at no cost.
There are several ways to spend less. Subscriptions run through Subscribe & Save, which takes 50% off the first two orders, and signing up to the email newsletter brings a £5 discount. NHS staff and healthcare workers can claim up to 30% off after verifying through Health Service Discounts, students get up to 44% off selected items via Student Beans, and a Refer-a-Friend link gives a friend a percentage off their first order while earning the referrer store credit. Newsletter subscribers may also receive a birthday discount covering topicals, gummies and accessories.
