How to choose NO3 Number Three haircare
NO3 Number Three is a Japanese professional haircare brand sold mostly through salons, and the lineup is organized into named series rather than a single one-size formula. The grid here runs across shampoos and treatments plus a few color products, so the choice comes down to your hair type, your scalp condition, and whether you want a matched wash-and-treat pair. This guide walks through the main lines we stock and how to pick the one that fits.
What NO3 Number Three is
NO3 Number Three is a salon haircare house known for splitting its range into distinct series, each tuned to a different need. Instead of one shampoo and one conditioner, you get families like Irga, Muriem, Hughcare, and Yururuka, with shampoos and matching treatments inside each. That structure is why picking a line matters more than picking a single product: the shampoo and treatment in a series are meant to work as a pair.
Shampoo and treatment as a pair
Most of the catalog falls into two buckets: cleansing shampoos and post-wash treatments. The shampoos clean the scalp and lift away buildup, while the treatments rebuild and soften the lengths after rinsing. For the best result, match a shampoo and a treatment from the same series, for example the Irga Shampoo with the Irga Treatment, or the Hughcare Shampoo with the Hughcare Treatment. Using the pair from one line keeps the scent and the conditioning level consistent.
The Irga line
Irga is one of the deepest series in this hub, and it includes both a standard shampoo and a medicinal version aimed at scalp care. You'll find the Irga Shampoo in a 250ml everyday size and the Irga Medicinal Shampoo in a larger 660ml bottle for heavier use. On the conditioning side, the Irga Treatment S in 200g pairs with these shampoos. Reach for Irga when your priority is a clean, balanced scalp alongside soft lengths.
Muriem, Hughcare, and Yururuka
Beyond Irga, the grid carries several other named series. Muriem appears here as the Muriem Home Milk 120g, a leave-style treatment for at-home use between salon visits. Hughcare runs as a full pair, with the Hughcare Shampoo 300ml and the Hughcare Treatment 200g. The Yururuka series shows up as treatments such as the Yururuka Ciprefluffi Treatment and the Yuruluka Floranalisi Treatment 620g, which lean toward soft, fluffy finishes for finer or limp hair.
Medicinal shampoos for the scalp
Several shampoos in this range carry a medicinal label, including the Irga Medicinal Shampoo and the Irga Medicinal Shampoo 660ml. These are formulated with scalp condition in mind rather than just cleansing the hair shaft, so they suit anyone dealing with an oily, flaky, or sensitive scalp. If a regular shampoo leaves your scalp feeling tight or congested, a medicinal option from the line is the one to test first.
Color and finishing products
The brand isn't only wash-and-treat. Items like Color Concert 80g sit on the color side of the catalog and are meant to support or refresh color-treated hair. If your hair is chemically processed, pairing a color-conscious product with a gentle shampoo and a rich treatment helps keep the tone looking fresh and the lengths from drying out. Color-treated hair is exactly where the matched-pair approach pays off most.
Picking the right size
NO3 Number Three products come in a range of sizes, and the right one depends on how often you wash and whether you're sampling or committing. Smaller bottles like the Irga Shampoo 250ml or the Muriem Home Milk 120g are easy ways to try a line before you scale up. The larger formats, such as the Irga Medicinal Shampoo 660ml or the Yuruluka Floranalisi Treatment 620g, work out better per use if you've already settled on a series and wash frequently.
Salon sourcing and authenticity
Because NO3 Number Three is a professional salon brand, it isn't always easy to find outside Japan, and the series names can be hard to track down individually. The items in this hub are stocked as genuine salon-grade products, so you can build a full routine from one place: a cleansing shampoo paired with its matching treatment, plus an at-home milk or color product to round things out. That makes it simple to recreate a salon wash-and-treat at home with the real lines.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What product lines does NO3 Number Three have?
The range is split into named series rather than one universal formula. In this hub you'll find the Irga line (including a medicinal shampoo), Hughcare shampoo and treatment, the Yururuka treatments such as Ciprefluffi and Floranalisi, the Muriem Home Milk, and color products like Color Concert. Each series carries its own shampoo and treatment meant to be used together.
Should I pair the NO3 shampoo and treatment from the same line?
Yes. The shampoos and treatments inside a series are tuned to match, so the Irga Shampoo works best with the Irga Treatment S, and the Hughcare Shampoo pairs with the Hughcare Treatment. Mixing across lines still cleans and conditions, but using a matched pair keeps the scent and the conditioning level consistent through the wash.
What is the difference between the Irga shampoo and the Irga Medicinal Shampoo?
The standard Irga Shampoo focuses on everyday cleansing of the hair and scalp, while the Irga Medicinal Shampoo is formulated with scalp condition in mind and comes in a larger 660ml size for heavier use. If your scalp gets oily or flaky after washing, the medicinal version is the one to try first.
Which NO3 products suit color-treated hair?
Color-conscious items like Color Concert 80g sit on the color side of the catalog and help support color-treated hair. Pair one with a gentle shampoo and a rich treatment from a line such as Yururuka to keep the lengths soft and the tone looking fresh, since chemically processed hair benefits most from the matched wash-and-treat approach.
Are the Yururuka treatments good for fine or limp hair?
The Yururuka series, including the Ciprefluffi Treatment and the Floranalisi Treatment 620g, leans toward soft, fluffy finishes that suit finer or limp hair. If a heavy treatment weighs your hair down, a Yururuka option tends to add softness without flattening the roots.
How do I use the Muriem Home Milk?
The Muriem Home Milk 120g is a leave-style treatment meant for at-home use between salon visits. Work a small amount through towel-dried lengths after washing to add softness and help maintain the condition you'd get from a salon treatment, without needing to rinse it out.
What sizes do NO3 Number Three products come in?
Sizes vary by product. Smaller bottles like the Irga Shampoo 250ml or the Muriem Home Milk 120g are an easy way to trial a line, while larger formats such as the Irga Medicinal Shampoo 660ml and the Yuruluka Floranalisi Treatment 620g work out better per use once you've settled on a series and wash often.
Is NO3 Number Three a genuine Japanese salon brand?
Yes. NO3 Number Three is a professional Japanese haircare house sold mainly through salons, which makes its individual series hard to find elsewhere. The items in this hub are stocked as genuine salon-grade products, so you can build a full routine of shampoo and matching treatment, plus an at-home milk, from one place.
