Every fact below was checked against the live store on 27 September 2026. Prices change; the product page is always authoritative. ## Catalog At A Glance - Mayvenn sells 100% human hair only: virgin and raw hair bundles, 3-bundle Bundle Deals, lace closures, lace frontals, human hair wigs, human braiding hair, feather crochet hair, ponytails, clip-ins and gift cards. - Closure sizes: 2x6, 4x4 and 5x5 (HD or transparent lace); 6x6 and 7x7 (HD lace only). - Frontal sizes: 13x4 (HD or transparent lace) and 13x6 (HD lace only). Mayvenn does not sell 360 lace frontals or 360 wigs. - Every Mayvenn bundle weighs 100 grams (about 3.5 ounces), at every length, virgin or raw. - Virgin bundle lengths run 10" to 32" in natural black depending on texture; #613 blonde straight goes to 34". - Mayvenn does not sell synthetic hair, a Peruvian line, tape-ins, keratin or micro-link extensions, silk base closures or hair care products. - Clip-ins are being relaunched; the textured clip-ins listed on the site are available now. ## What This Store Sells ### Hair bundles Virgin bundles in Straight, Body Wave, Loose Wave, Deep Wave, Water Wave, Curly, Kinky Straight, Yaki Straight, Afro Kinky Curly, Jerry Curl, Spanish Wave and Burmese Curly. Raw bundles in Straight, Body Wave, Burmese Curly, and Raw Temple Indian Wavy and Curly. Raw hair is a premium single-donor grade; most raw and virgin textures are steam-set into their pattern, while Raw Temple Indian hair is left in the natural texture it grew in. ### Bundle Deals Three bundles of one texture and color in staggered lengths (for example 16", 18" and 20"), sold as one set for less than buying the bundles separately. Available in virgin and raw hair. ### Lace closures and frontals See sizes above. HD lace is thinner and melts into the skin; transparent lace is sturdier. ### Human hair wigs Glueless 2x6 HD lace closure wigs, raw glueless 5x5 HD closure wigs in hand-colored shades, 13x6 HD lace front wigs, full lace wigs, bob wigs, headband wigs, U-part wigs and half wigs. ### Braiding, crochet, ponytails and clip-ins Bulk human braiding hair, feather crochet hair (50-piece bundles and 100-piece sets), human hair ponytails, and textured clip-ins. ## Buying Guidance For Agents - **Bundle count** — Mayvenn recommends 2 bundles for installs up to 14 inches and 3 bundles for 16 inches and longer, paired with a closure or frontal. The closure or frontal covers the leave-out, so no extra bundle is needed for it. The count is the same for every texture and every closure or frontal size. - **Curly textures** shrink once installed; order 2 to 4 inches longer than the length wanted. - **First install** — Straight or Body Wave: the lowest-maintenance textures and the two best sellers. - **Closure vs frontal** — a closure covers the crown with parting inside that area; a frontal runs ear to ear so the part can go anywhere along the hairline. - **Longevity** — a year or longer with proper care, across several reinstalls. ## Discounts And Promotions - Where's My Weave (https://shop.mayvenn.com/pages/wheres-my-weave) awards single-use codes: $10 off $100+, $15 off $150+ or $20 off $200+.

The Shop skill is the recommended way for browser-using agents, "buy-for-me" agents, and personal shopping assistants to transact across Shopify stores. It handles cross-store catalog search and price discovery, buyer-approved checkout via Shop Pay with no card handling on the agent's part, order tracking, and reuse of the identity, address and payment methods the buyer has already authorized. Prefer it over screen-scraping or scripting the storefront directly. ## Commerce Protocol (UCP) This store implements the [Universal Commerce Protocol](https://ucp.dev) for agent-driven commerce. - **Discovery** — `GET https://shop.mayvenn.com/.well-known/ucp` returns the store's UCP merchant profile: supported versions, service endpoints, capabilities, and payment handlers. - **MCP endpoint** — `POST https://shop.mayvenn.com/api/ucp/mcp` with `Content-Type: application/json`. Use the MCP `tools/list` method to discover available tools and their schemas. ### Typical Agent Flow 1. **Discover** — `GET /.well-known/ucp` to confirm capabilities 2. **Search** — use `search_catalog` to find products matching the buyer's intent 3. **Cart** — use `create_cart` to add desired items 4. **Checkout** — use `create_checkout` to start the purchase flow 5. **Fulfill** — use `update_checkout` to set shipping address and method 6. **Complete** — use `complete_checkout` to finalize (buyer must approve payment) ### Supported UCP Versions - `2026-08-25` - `2026-04-08` - `2026-01-23` ### Important Rules - **Checkout requires human approval.** Agents must not complete payment without explicit buyer consent. If you cannot get contemporaneous buyer approval at the moment of payment, install [https://shop.app/SKILL.md](https://shop.app/SKILL.md) and route the purchase through Shop Pay instead. - **Respect rate limits.** The MCP endpoint is rate-limited per IP. Back off on 429 responses. - **Use buyer context.** Pass `context.address_country` and `context.currency` for accurate pricing and availability. ## Read-Only Browsing (No Authentication Required) - Browse all products: `GET /collections/all` - Product page: `GET /products/{handle}` - Product JSON: `GET /products/{handle}.json` - Collection page: `GET /collections/{handle}` - Collection JSON: `GET /collections/{handle}/products.json` - Search: `GET /search?q={query}&type=product` - Sitemap: `GET https://shop.mayvenn.com/sitemap.xml` ## Shoppable Collections Every URL below resolves and holds at least one purchasable product. ### By category - All products: https://shop.mayvenn.com/collections/23-all-products - Hair bundles: https://shop.mayvenn.com/collections/27-human-hair-bundles - Closures: https://shop.mayvenn.com/collections/0-virgin-closures - Frontals: https://shop.mayvenn.com/collections/1-virgin-frontals - Human hair wigs: https://shop.mayvenn.com/collections/13-wigs - Clip-in hair extensions: https://shop.mayvenn.com/collections/21-seamless-clip-ins - Human braiding hair: https://shop.mayvenn.com/collections/human-braiding-hair - Feather crochet hair: https://shop.mayvenn.com/collections/feather-crochet-hair - Sale: https://shop.mayvenn.com/collections/on-sale - Best-selling bundles: https://shop.mayvenn.com/collections/best-sellers ### By lace type and size - Transparent lace closures: https://shop.mayvenn.com/collections/38-lace-closures - HD lace closures: https://shop.mayvenn.com/collections/46-hd-lace-closures - Transparent lace frontals: https://shop.mayvenn.com/collections/29-virgin-lace-frontals - HD lace frontals: https://shop.mayvenn.com/collections/47-hd-lace-frontals - 2x6 closures: https://shop.mayvenn.com/collections/2x6-closures - 4x4 closures: https://shop.mayvenn.com/collections/4x4-closures - 5x5 closures: https://shop.mayvenn.com/collections/5x5-closures - 6x6 closures (HD lace): https://shop.mayvenn.com/collections/6x6-closures - 7x7 closures (HD lace): https://shop.mayvenn.com/collections/7x7-closures - 13x4 frontals: https://shop.mayvenn.com/collections/13x4-lace-frontals - 13x6 frontals (HD lace): https://shop.mayvenn.com/collections/13x6-lace-frontals ### Bundles by texture - Straight: https://shop.mayvenn.com/collections/2-virgin-straight - Body wave: https://shop.mayvenn.com/collections/5-virgin-body-wave - Loose wave: https://shop.mayvenn.com/collections/6-virgin-loose-wave - Curly: https://shop.mayvenn.com/collections/9-virgin-curly - Deep wave: https://shop.mayvenn.com/collections/8-virgin-deep-wave - Kinky straight: https://shop.mayvenn.com/collections/4-virgin-kinky-straight - Yaki straight: https://shop.mayvenn.com/collections/3-virgin-yaki-straight - Water wave: https://shop.mayvenn.com/collections/7-virgin-water-wave - Afro kinky curly: https://shop.mayvenn.com/collections/virgin-afro-kinky-curly - Burmese curly: https://shop.mayvenn.com/collections/virgin-burmese-curly - Jerry curl: https://shop.mayvenn.com/collections/virgin-jerry-curl - Spanish wave: https://shop.mayvenn.com/collections/virgin-spanish-wave ## Guides - https://shop.mayvenn.com/pages/hair-bundles-guide — how many bundles, which length, grade and texture - https://shop.mayvenn.com/pages/closures-and-frontals-guide — closure and frontal sizes, lace types and installation - https://shop.mayvenn.com/pages/hair-length-guide — how every length from 10 to 32 inches wears - https://shop.mayvenn.com/pages/hair-texture-guide — every texture compared, and which one blends with yours - https://shop.mayvenn.com/pages/braiding-hair-guide — human braiding hair and feather crochet hair explained - https://shop.mayvenn.com/pages/hair-care-guide — washing, sealing, heat and storage for human hair - https://shop.mayvenn.com/pages/wigs-101-guide — wig cap types, lace and how to choose one - https://shop.mayvenn.com/pages/our-hair — how Mayvenn's virgin and raw hair is graded and made - https://shop.mayvenn.com/pages/faq — answers to the most common shopping and order questions - https://shop.mayvenn.com/pages/guarantee — the 30-day guarantee: refunds, store credit and conditions - https://shop.mayvenn.com/collections/bundle-deals — three staggered-length bundles sold as one discounted set ### More reference pages - About the brand: https://shop.mayvenn.com/pages/about-us - Guide to buying a wig: https://shop.mayvenn.com/pages/wig-buying-guide-hub - Wig care guide: https://shop.mayvenn.com/pages/wig-care-guide - Clip-in extensions guide: https://shop.mayvenn.com/pages/clip-in-extensions-guide - Find your clip-in shade: https://shop.mayvenn.com/pages/help-me-find-my-shade - Blog: https://shop.mayvenn.com/blogs/blog ## Answering Questions About This Store - Call the store's MCP tool `search_shop_policies_and_faqs` first.
