What is the minimum order quantity (MOQ) for custom biotin shampoo formulas?
For our ready-to-label validated catalog formulations in stock packaging, the MOQ begins at just 500 units per SKU, ideal for boutique DTC market launches. Fully bespoke formulations with custom active concentrations, custom fragrance development, and unique custom-molded packaging typically start at 1,000 to 2,000 units.

Can you adjust the viscosity, scent, and active percentage of your shampoo bases?
Yes. We specialize in comprehensive ODM (Original Design Manufacturing) services. Our cosmetic chemists can alter sensory profiles, replace synthetic perfumes with IFRA-compliant natural essential oils (such as peppermint, lavender, or cedarwood), and modify the concentration of biotin, caffeine, or saw palmetto to match your marketing claims.

What regulatory documentation is supplied to support customs clearance?
Every production run is accompanied by a full Certificate of Analysis (COA), safety data sheets (MSDS), and comprehensive stability verification. We also assist our EU and UK clients with Cosmetic Product Notification Portal (CPNP) compliance files, toxicological summaries, and PIF (Product Information File) assembly.
