No3 Number Three Treatment

NO3 NUMBER THREE is a Japanese professional beauty brand that started in the salon industry. The brand number "3" references a three-step philosophy of cleanse, treat, and protect. Their treatments are used in Japanese salons and sold in professional sizes, which is why you see them listed in both 200g and 620g formats.

The brand focuses on precision formulas rather than broad claims - each product line addresses a defined hair problem. Hughcare targets damage repair for bleached or repeatedly processed hair, while Yururuka lines focus on smoothing and defrizzing. This specialist approach is the reason the brand built a following among colorists and stylists.

The Hughcare Treatment is available in 200g and 620g sizes. It is formulated specifically for hair that has been bleached, highlighted, or color-treated multiple times. The formula works to reduce breakage and restore elasticity that chemical processes strip away.

If you bleach or lighten your hair regularly, the 620g size gives you several months of use and costs less per gram than the smaller jar. The 200g is a good starting size if you are trying Hughcare for the first time or want a travel option. Use it two to three times per week for the first month after a color service, then weekly for maintenance.

Irga Treatment S comes in 200g and 620g. The "S" designation in the name stands for "stiff" - this line is built for hair that feels wiry, coarse, or resistant to smoothing. It contains softening agents that work on the hair shaft's outer cuticle layer to reduce rigidity without weighing hair down.

Coarse hair, particularly wavy or naturally thick hair, tends to absorb product unevenly. Irga S has a slightly heavier consistency than the Hughcare line, which helps it coat each strand more fully. Leave it on for at least five minutes under a shower cap to allow the actives to penetrate before rinsing.

The Yururuka family includes three distinct treatments: Ciprefluffi, Floranalisi (620g), and Flora Repair (620g), plus the Herbal Bamboo variant (200g). Each brings a different botanical focus while sharing the Yururuka smoothing base. Ciprefluffi addresses frizz with a lighter, more fluid texture; Floranalisi emphasizes floral and repair actives; Flora Repair concentrates on nourishment after heat styling; and Herbal Bamboo uses bamboo and herbal extracts for scalp-adjacent nourishment.

The Yururuka range is the most fragrance-forward in the NO3 NUMBER THREE lineup. If scent matters to you, the Floranalisi and Flora Repair options are notably aromatic. For fragrance-sensitive users, the Ciprefluffi version has a lighter scent profile.

The Proaction Four Seed Treatment is available in 150ml and 1000g - the largest size in the NO3 NUMBER THREE range available here. The "four seed" name refers to four plant seed oils blended into the formula: their combined fatty-acid profiles address both surface conditioning and deeper cortex hydration.

The 1000g size is a professional salon jar. It makes the most sense if you have long or thick hair, use treatment weekly, or want to share it across a household. At 1000g it offers the lowest cost per application of any treatment in this collection. The 150ml is a pouch-style or tube format suitable for gym bags or carry-on travel.

Most NO3 NUMBER THREE treatments come in a 200g and a 620g variant. The 200g fits roughly 10-15 full-head applications for shoulder-length hair; the 620g extends that to 30-50 applications depending on thickness and length. For hair that sits above the shoulders, the 200g is sufficient for a multi-month trial run. For waist-length or very thick hair, the 620g is cost-effective from the start.

The Proaction Four Seed 1000g jar is the only professional bulk format in the collection. It is not a salon exclusive - it can be ordered like any other product - but its size is designed for frequent heavy use. Avoid the 1000g if you are still deciding whether you like the formula; commit to a 150ml or 200g first.

Apply treatment to freshly shampooed, towel-damp hair. For the Irga S and Proaction Four Seed lines, section thick hair before applying to ensure even coverage root to mid-length - these are denser formulas. For Yururuka and Hughcare, you can apply directly to the wet mass and work through with fingers or a wide-tooth comb.

Leave time matters: the brand recommends a minimum of three minutes for a quick conditioning pass, but five to ten minutes with a shower cap produces noticeably better results for damaged or coarse hair. Rinse thoroughly with cool water to close the cuticle. Do not leave these treatments in - they are all rinse-out formulas only. Follow with NO3 NUMBER THREE conditioner or a scalp serum if your routine includes one.

Bleached or color-processed hair: Hughcare Treatment. Its repair focus makes it the right fit for fragile strands. Thick, coarse, or resistant hair: Irga Treatment S. The heavier base penetrates wiry textures better than the lighter Yururuka options. Frizzy or wavy but not damaged: any Yururuka variant depending on your scent and botanical preference. Frequent heat stylers: Yururuka Flora Repair Treatment, which has specific heat-protection actives in its formula. Need a large professional supply or have very long thick hair: Proaction Four Seed 1000g.

If your hair has multiple concerns - for example, color-treated and coarse - start with Hughcare for the first two months post-service, then switch to Irga S for maintenance. You can also apply Hughcare to the ends and lengths while using Irga S at the mid-shaft if you have a layered damage pattern.
