Bon Cosmetic

BON Cosmetic sits on the salon-supply side of Korean beauty rather than the sheet-mask side. The grid here is hair and scalp: keratin silky essences, the Aurora PPT treatment, henna colour kits, a cooling sherbet shampoo, glucosamine massage cream, and oxidizing developers. Sizes run large because the buyer is often a stylist or someone who colours and treats their own hair at home and wants enough product to last. Treat this as a professional hair line and the catalogue makes sense.

Two keratin essences anchor the range. The Alpha Keratin Silky Essence 180ml and the Pakeratin Silky Essence 180ml are leave-in smoothing essences meant to seal a rough or chemically treated cuticle and add slip. They are the everyday step in the line, the thing you reach for after washing to tame frizz and add shine. The 180ml bottle holds enough for repeated home use, so a single bottle stretches across many washes.

For damage repair the line steps up to the Aurora PPT Treatment 500ml. PPT (polypeptide) treatments target hair that has been bleached, permed, or coloured, filling the gaps where protein has been stripped. The 500ml format is salon size, enough for a back-bar pump or a few months of weekly masks at home. Pair the PPT treatment with one of the keratin essences and you have a wash-day repair routine: deep treatment first, leave-in essence to finish.

BON Cosmetic carries plant-based colour too. The 100g Natural Aurora Henna and the Aurora Breechs sets are for people who prefer henna and botanical dyes over straight chemical colour. Henna deposits a warm tone and coats the strand rather than lifting it, so it behaves differently from a permanent dye and does not need a developer. If you want gentler, gradual colour or are covering early greys, this is the part of the range to look at.

The 6 Pro 20vol Oxidizer 150ml is a cream developer, the activator you mix with permanent colour or lightener. The "20vol" (20 volume, roughly 6% peroxide) is the standard strength for grey coverage and a level or two of lift, which is why it is the one stocked here. Developer is only half of a colour service, so if you are buying it you will also need a compatible colour or henna and a clear sense of your mixing ratio. This is the most pro-only item in the collection; skip it unless you colour hair deliberately.

On the cleansing side, the Sherbet Cool Shampoo 1000ml and the Herbal Pack 1000ml cover wash and scalp care. The cool shampoo gives a menthol-style tingle that suits oily scalps and hot weather, and the litre bottle is built for frequent washing or a household sharing one bottle. The herbal pack is a scalp-and-hair mask step. Both run at salon volume, so they are economical per wash compared with small retail bottles.

Size is the first decision in this collection. The 1000ml shampoos and the 500ml PPT treatment are made for a working back bar or someone who colours and treats hair regularly enough to finish a big bottle. The 180ml keratin essences and 150ml oxidizer are more personal-use portions. If you are testing the brand, start with a 180ml essence; if you already know you want it as a staple, the litre formats bring the per-use cost down.

The lines are designed to stack. A full BON Cosmetic wash day runs shampoo to cleanse, herbal pack or PPT treatment for the deep-repair step, then a keratin silky essence as the leave-in finish. Colour and developer sit outside that routine as a separate service when you are dyeing. Buying one item from each step gives you a complete salon-style regimen rather than a single product with nothing to support it.

BON Cosmetic is a Korean brand, and these salon formats are not easy to find outside Korea. We list 20+ of its hair and scalp products and ship them internationally with tracking, so you can stock keratin essences, henna, and litre shampoos that would otherwise stay inside the Korean professional market. Because the bottles are large, plan your order around the sizes you will realistically use before they expire.
