Welcos Treatment
WELCOS built its treatment line around the Confume and Mugens ranges, hair care made to repair damage from coloring, heat styling, and everyday washing. This collection gathers 72 in-stock WELCOS treatments: rinse-off masks in bulk 500ml-1000ml sizes for salons and heavy users, leave-in argan oils for daily frizz control, and keratin ampoule treatments for chemically treated hair. Argan oil shows up across several product lines here, both as a stand-alone oil and blended into shampoos and packs, so you can build a full routine from one brand instead of mixing incompatible actives.
Buying guide
WELCOS Treatment Guide
WELCOS splits its treatment catalog into a few clear families: rinse-off masks for weekly deep conditioning, leave-in argan oils for daily use, and targeted ampoule treatments for damaged or chemically processed hair. This guide walks through what is actually different between the Confume, Mugens, and Fruitland lines carried in this collection so you can match a treatment to your hair type and routine instead of guessing from the label.
Confume Two-Face Treatment: the dual-side mask
The Confume Two-Face Treatment 530ml is built around a two-sided approach: one side conditions the mid-lengths, the other targets the ends where damage concentrates. It works as a weekly rinse-off mask rather than a daily conditioner, applied after shampooing and rinsed out after a few minutes.
Confume Argan Gold Treatment
The Confume Argan Gold Treatment 200ml is the smaller-format version of the argan-based rinse-off line, sized for regular home use rather than salon volume. It pairs argan oil with a richer cream base meant for dry or color-treated hair that needs more slip during detangling.
Argan Treatment Oil: leave-in options
Several products in this collection are pure leave-in oils rather than rinse-off masks: the Argan Treatment Oil 120ml+25ml travel set, the Forest Story Argan Treatment Oil 120ml, and the Argan Treatment Spray Froesh Floral, sold as a 5-pack of 300ml bottles. These apply to towel-dried or dry hair to control frizz and add shine without rinsing.
Mugens Zencare and keratin treatments
The Mugens line covers two different jobs. Mugens Zencare SS Treatment 500ml is a rinse-off conditioning mask sized for frequent use, while the Mugens The MDL Keratin Treatment 150ml is a smaller, more concentrated formula aimed at rebuilding hair that has been bleached or repeatedly colored.
Treatment shampoos vs. rinse-off treatments
Not everything here is a leave-on or rinse-out mask. The Rich Moisture Treatment Shampoo Acid 1000ml and Mugens Rich Moisture Treatment Shampoo 1L are pH-balanced cleansing shampoos formulated to pair with the rinse-off treatments in this collection, so the cleansing step does not strip out what the mask deposits.
Bulk salon sizes vs. travel sets
WELCOS treatments in this collection span a wide size range: 1000ml shampoo and hair-pack jugs meant for salon or high-frequency home use, down to a 120ml+25ml argan oil travel duo. Check the listed volume before ordering if you are stocking a salon versus buying for personal use, since the per-ml value differs significantly between formats.
Choosing a treatment by hair condition
For everyday dryness or frizz, the leave-in argan oils and sprays are the lower-commitment option. For chemically processed hair (bleach, perm, repeated color), the keratin ampoule treatment and the rinse-off masks with richer cream bases address structural damage rather than just surface shine. Combining a rinse-off mask with a leave-in oil is a common two-step routine within this same brand.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What is the difference between WELCOS Confume and Mugens treatments?
Confume and Mugens are separate WELCOS product lines rather than the same formula relabeled. Confume covers the Two-Face Treatment and Argan Gold Treatment, both rinse-off masks built around argan oil for general dryness. Mugens covers the Zencare SS Treatment, a rinse-off conditioning mask, and the MDL Keratin Treatment, a smaller-format formula targeted at chemically damaged hair. Pick Mugens keratin if your hair has been bleached or permed; pick Confume argan-based masks for general dryness maintenance.
Are the WELCOS argan treatment oils leave-in or rinse-out?
The argan-labeled oils and sprays in this collection, including the Argan Treatment Oil 120ml+25ml set, the Forest Story Argan Treatment Oil, and the Argan Treatment Spray Froesh Floral, are leave-in products applied to towel-dried or dry hair. They are separate from the argan-based rinse-off masks like Confume Argan Gold Treatment, which are washed out after a few minutes on wet hair.
What sizes do WELCOS treatments come in?
Sizes in this collection range from a 120ml+25ml argan oil travel duo up to 1000ml shampoo and hair-pack jugs meant for salon or heavy home use. Mid-size options like the 500ml Confume Two-Face Treatment and 500ml Mugens Zencare SS Treatment sit between the two, sized for regular single-household use rather than travel or bulk salon stock.
Do I need to use the WELCOS treatment shampoo with a matching mask?
The Rich Moisture Treatment Shampoo Acid and Mugens Rich Moisture Treatment Shampoo are pH-balanced cleansers formulated to work with the rinse-off treatments in this same collection, so the cleansing step does not strip what the follow-up mask deposits. They are not exclusive to one mask, but pairing a WELCOS treatment shampoo with a WELCOS rinse-off mask keeps the pH and residue behavior consistent through the whole wash routine.
Is WELCOS treatment safe for color-treated or bleached hair?
The Mugens The MDL Keratin Treatment is specifically formulated for chemically processed hair, including bleached or repeatedly colored hair, and is the most concentrated repair option in this collection. The Confume and Fruitland argan-based masks and oils are gentler daily or weekly options suited to general dryness rather than heavy chemical damage, so match the keratin treatment to more aggressively processed hair.
