Welcos

WELCOS is a Korean personal-care brand that built its name on hair products rather than skincare serums. The lineup we carry reflects that, with Argan ceramide treatments, acid-pH moisture shampoos, and perm chemistry all sitting side by side. If you came looking for sheet masks, this is not that brand. What you get instead is workhorse haircare in big bottles, sold at the price a Korean drugstore charges rather than a boutique markup.

The Argan family is the heart of the range. The Argan Treatment Oil (120ml plus a 25ml travel top-up) is a leave-in finishing oil you smooth through damp or dry mid-lengths and ends to tame frizz and add shine. The Argan Ceramide Hair Pack in the 1000ml tub is the deeper rinse-out mask, formulated with ceramide to help rebuild the look of dry, bleached, or heat-damaged hair. Use the pack once or twice a week in the shower and keep the oil for daily styling.

The Rich Moisture Treatment Shampoo is an acid-pH (slightly acidic) cleanser sold in a 1000ml bottle. A mildly acidic shampoo helps the cuticle lie flat, which keeps colour-treated and chemically processed hair looking smoother and less frizzy than a high-pH lather would. It pairs naturally with the Argan pack: cleanse with the acid shampoo, then condition with the ceramide treatment. The litre size makes it a sensible buy for long hair or a household that goes through shampoo quickly.

The SB Neutralizer and HP Neutralizer (each a 1000ml bottle) are the second-step chemistry in a cold perm or straightening service. After the waving lotion reshapes the hair, the neutralizer re-fixes the bonds so the new curl or straightening holds. These are professional-leaning products meant for someone who knows perm processing, whether a salon or an experienced home user. If you are not doing chemical texturing, you can skip this section entirely and stay with the wash-and-treat lineup.

The Hasuo Oriental Rinse comes in a generous 1500ml bottle and draws on the Korean tradition of herbal hair care (hasuo refers to fo-ti, an herb long used for hair). It works as a conditioning rinse for people who like a botanical, traditional feel rather than a heavy silicone slip. The large size and the gentle, everyday character make it a good family-bathroom staple to alternate with the richer Argan pack on days your hair does not need deep repair.

Around the core hair lineup WELCOS rounds things out with everyday extras. You'll find the Confum hair styling pieces for hold and finish and the Modern Crepas firming item for the face and body, plus the Neonis IEX emulsion among the skin-side products. These are the kind of low-key, refill-it-without-thinking products that fill the gaps in a routine. Read each product page for the exact use, since this corner of the range mixes hair, scalp, and body items.

The Prolance Nail Remover ships as a 3-pack of acetone remover, a simple but genuinely useful staple for anyone who does gel or regular polish at home. Buying the multipack means you keep a spare under the sink instead of running out mid-manicure. It is not glamorous, but it is one of those quiet repeat-purchase items that make WELCOS feel like a Korean household brand rather than a one-category label.

Most of the WELCOS hair products land in 1000ml or 1500ml bottles, so a single purchase lasts months and the per-use cost stays low. That bulk format is the brand's value proposition: salon-volume bottles at retail prices. For a first order, a sensible starter set is the Rich Moisture acid shampoo plus the Argan Ceramide pack, adding the Argan finishing oil if you style with heat. Keep the neutralizers strictly for actual perm work, and grab the nail remover multipack while you are here.

Every WELCOS product on this page is the Korean-market formula, sourced and shipped from Korea so you get exactly what is sold there rather than a reformulated export edition. That matters most for the salon chemistry and the acid-pH shampoo, where the formulation is the whole point.
