Hair Plus
HAiR Plus is a Korean haircare brand built around repairing damaged hair from the inside out. The range splits into three jobs: the Protein Bond line (ampoule, treatment, shampoo, and a moisturising hair mist) rebuilds bonds in bleached or over-processed hair, the Silk Coating shampoo and treatment smooth frizz and add slip, and the Shizu shampoo targets thinning and hair-loss concerns. We list 42+ HAiR Plus products here, in sizes from a 35ml ampoule and 50ml travel treatments up to 1000ml salon bottles, plus the Ultra-damaged Hair Protein Clinic gift set for a full repair routine.

Buying guide
The HAiR Plus Buying Guide
HAiR Plus is a Korean haircare brand for hair that has been put through the wringer: bleach, repeated colour, heat styling, or just years of wear. The range is organised around three concerns rather than scattered one-offs, so once you know whether your problem is broken bonds, frizz, or thinning, the shortlist gets short fast. This guide explains what each line does, how the sizes work, and how to put a repair routine together.
What HAiR Plus Is For
This is a damage-repair and treatment brand, not a basic wash-and-go shampoo line. The whole catalogue points at one outcome: hair that has lost strength or smoothness getting some of it back. If your hair is healthy and you just want a gentle daily cleanser, this range is more than you need. If it snaps, tangles, frizzes, or feels straw-like after bleaching, this is the right aisle.
The Protein Bond Line
The Protein Bond family is the core of the brand and the part most people come for. It rebuilds the internal bonds that bleach and chemical processing break, which is what leaves hair weak and stretchy when wet. The line spans several steps: the Protein Bond Ampoule (35ml) is a concentrated leave-in shot for the worst-damaged lengths, the Protein Bond Treatment comes in a travel 50ml and a salon-size 690ml, the Protein Bond Shampoo cleanses without stripping, and the Moist Water Essence Hair Mist (200ml) tops up hydration between washes. There is also a NEW Protein Treatment (700ml) if you want a large tub for frequent use.
Silk Coating for Smoothness
Where the Protein Bond line is about strength, the Silk Coating line is about surface feel. The Silk Coated Shampoo (1000ml) and Silk Coating Treatment (1000ml) lay a smoothing layer over the hair shaft to cut frizz, add slip, and make detangling easier. These are the products to reach for if your main complaint is roughness, flyaways, or hair that catches on a comb rather than outright breakage. Many people pair a Silk Coating wash with a Protein Bond treatment for both effects.
Shizu for Thinning Hair
The Shizu Women Hair Loss Shampoo (500ml) addresses a different concern entirely: scalp and thinning. It is formulated as a hair-loss-care cleanser aimed at women noticing reduced density or more shedding. If repair and smoothness are not your issue but volume and scalp health are, this is the HAiR Plus product to start with. It can sit in the same routine as the treatments, used as your everyday shampoo while the Protein Bond steps handle the lengths.
Match the Line to Your Concern
The quickest way to choose is to name the problem. Broken, stretchy, post-bleach hair points to the Protein Bond Ampoule and Treatment. Frizz and rough texture point to the Silk Coating shampoo and treatment. Thinning or shedding points to the Shizu shampoo. Most people have one dominant concern and a secondary one, so a common combination is a Protein Bond treatment for repair plus a Silk Coating shampoo for daily smoothness.
Building a Repair Routine
A full HAiR Plus routine runs cleanse, treat, leave-in. Wash with the Protein Bond or Silk Coated Shampoo, work a treatment through the mid-lengths and ends in the shower, rinse, then on the worst sections add the Protein Bond Ampoule as a leave-in once towel-dried. Between washes, the Moist Water Essence Hair Mist keeps lengths from drying out. You do not need every product at once; build up as your hair tells you what it still needs.
Sizes: Travel, Full, and Salon
Several products come in more than one size, which makes trialling cheap. The Protein Bond Treatment and Shampoo both have 50ml versions, ideal for a first try or for travel, alongside the big 690ml and 1000ml salon bottles for regulars. The Ultra-damaged Hair Protein Clinic Gift Set bundles steps together and is the simplest way to test a whole repair routine before committing to full sizes. For a product you already use weekly, the large bottle is the better value per use.
How Often to Treat
Protein repair is something to dose rather than overdo. Badly damaged hair benefits from a bond treatment one to a few times a week, with the ampoule reserved for the most fragile sections, while the milder Silk Coating and Shizu shampoos can be your everyday wash. Heat-styled or freshly bleached hair will want the treatments more often at first, then less as strength returns. Let the hair's feel guide the frequency rather than treating on a fixed schedule.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
Which HAiR Plus product should I buy first?
Match it to your main concern. For bleached or broken hair, start with a Protein Bond Treatment and add the Protein Bond Ampoule for the worst sections. For frizz and rough texture, start with the Silk Coating shampoo and treatment. For thinning, start with the Shizu Women Hair Loss Shampoo. If you want to test several steps at once, the Ultra-damaged Hair Protein Clinic Gift Set is the easiest entry.
What is the difference between the Protein Bond and Silk Coating lines?
They fix different problems. The Protein Bond line rebuilds the internal bonds that bleach and chemical processing break, so it targets weakness and breakage. The Silk Coating line smooths the surface of the hair to cut frizz and add slip, so it targets roughness and flyaways. If your hair snaps, choose Protein Bond; if it just feels rough, choose Silk Coating. Many people use one of each.
What is the Protein Bond Ampoule (35ml) for?
It is a concentrated leave-in shot for the most damaged lengths. After washing and towel-drying, you work a small amount through the driest, most fragile sections rather than the whole head. Because it is concentrated, the 35ml bottle lasts longer than the size suggests. Use it on top of a Protein Bond Treatment for badly bleached or over-processed hair.
Does the Shizu shampoo actually help with hair loss?
The Shizu Women Hair Loss Shampoo (500ml) is formulated as a hair-loss-care cleanser aimed at women noticing thinning or extra shedding. It works on the scalp and density side of things rather than repairing the lengths, so it is the HAiR Plus product to start with if volume and scalp health are your concern. You can use it as your everyday shampoo while Protein Bond treatments handle damage on the lengths.
How do I use the HAiR Plus products together?
The order is cleanse, treat, leave-in. Wash with a Protein Bond or Silk Coated Shampoo, work a treatment through the mid-lengths and ends in the shower and rinse, then on the worst sections add the Protein Bond Ampoule as a leave-in once towel-dried. Between washes, the Moist Water Essence Hair Mist tops up hydration. You do not need every step at once.
How often should I use a HAiR Plus protein treatment?
Dose it rather than overdo it. Badly damaged hair benefits from a bond treatment one to a few times a week, with the ampoule kept for the most fragile sections. Freshly bleached or heat-styled hair will want it more often at first, then less as strength returns. The Silk Coating and Shizu shampoos are mild enough for everyday washing.
What does the Protein Bond Moist Water Essence Hair Mist do?
The 200ml hair mist is a between-wash top-up that keeps dry, damaged lengths from feeling brittle. You spritz it onto mid-lengths and ends on non-wash days or before styling. It is a light hydration step rather than a deep treatment, so it complements the Protein Bond Treatment and Ampoule rather than replacing them.
Is the Protein Bond line suitable for bleached or colour-treated hair?
Yes, that is exactly what it is built for. Bleaching and repeated colour break the internal bonds that keep hair strong, which is why processed hair stretches and snaps when wet. The Protein Bond Treatment and Ampoule rebuild those bonds, and the Protein Bond Shampoo cleanses without stripping. For heavily processed hair, use the treatment regularly and reserve the ampoule for the most damaged sections.
Should I buy the small or the large HAiR Plus bottles?
Buy small to test, then size up what you keep using. The Protein Bond Treatment and Shampoo both come in 50ml travel sizes, perfect for a first try, alongside the 690ml and 1000ml salon bottles for regulars. The larger bottle is the better cost per use once a product earns a permanent place in your routine.
Is the Ultra-damaged Hair Protein Clinic Gift Set worth it?
It is the simplest way to test a full repair routine in one purchase. The set bundles HAiR Plus protein-repair steps together so you can see how cleanse, treat, and leave-in work on your own hair before committing to full sizes. If your hair is heavily bleached or over-processed and you are new to the brand, it is a sensible starting point.
