KYIR is a direct-to-consumer hair care brand operating at lovekyir.com. The brand positions itself around three core claims: safe for all skin types, dermatologist tested, and cruelty free. Its product lineup centers on topical hair serums, scalp stimulation tools, and an oral hair supplement, targeting consumers concerned with hair thinning and scalp health.

The flagship product, the Fuller Active Hair Serum (50ml/1.7oz), retails at $74.00 USD and carries an impressive on-site customer rating of 4.88 out of 5.0 from 81 reviews. Bundles such as the 2-bottle (60-day) option at $133.20 (down from $148.00) and the 3-bottle (90-day) option at $188.70 offer incremental savings. The Stimulating Scalp Duo bundle is priced at $95.40 (originally $106.00), and the Healthier Hair Supplement retails at $72.00 with a perfect 5.0/5.0 rating from 7 reviews.

KYIR ships to over 28 countries including the US, Canada, UK, Australia, and much of Europe and Asia. Free shipping is available on US orders over $100. International orders are handled through carriers such as DHL, FedEx, and UPS, with estimated delivery times of 7–21 business days. Canadian customers should note that shipments are made under DDU (Delivered Duty Unpaid) terms, meaning import duties are the buyer's responsibility. The brand advertises a 90-day money-back guarantee, though the dedicated return and shipping policy pages currently return 404 errors, which may limit pre-purchase transparency.
