There is a particular frustration in loving your colour but wishing your hair felt better. The blonde is luminous, the brunette beautifully nuanced, yet the ends catch on your brush and the lengths have lost their softness. You want the movement, touch and shine to be as considered as the shade.
At Paul Edmonds London, colour and condition are part of the same conversation. The blonde brief we’re hearing in the salon is for a fuller result with an easier grow-out, brightness through the lengths, blended into a softer root for a look that feels lived-in from the start. Creating that brightness can leave some sections more sensitised than others.
Whether you choose a full blonde, delicate soft blonde or a dimensional brunette, the finish depends on the condition beneath it. The care you take home should reflect both your colour and what your hair needs.
Shu Uemura Ultimate Reset is the range we turn to for very damaged, over-processed lengths. Its new Ultimate Reset Leave-In Mask also offers targeted care where lightening has left particular sections more fragile. Apply it to towel-dried mid-lengths and ends, leave it in and style a simple treatment step for clients who want beautiful colour and an uncomplicated routine between appointments.
“Clients want a fuller blonde with a softer grow-out. I consider the lightening history alongside heat styling and everyday wear, because some sections need more care than others. A targeted leave-in step makes that care easier to fit into the home routine.”
- Paul Edmonds
WHY RICE BELONGS IN A REPAIR ROUTINE
Rice brings more than Japanese heritage to Ultimate Reset. Its extract is valued for a nutrient profile that includes B vitamins, vitamin E, minerals and antioxidant compounds. Vitamin E is itself an antioxidant. Antioxidants are of interest in haircare because oxidation can affect the proteins and natural lipids that contribute to the condition of the hair fibre, particularly lengths already sensitised by colour or lightening.
For damaged hair, the practical role of rice extract is conditioning. In the new mask it appears as hydrolysed rice extract, a processed rice-derived ingredient recognised for helping hair feel softer, more supple and easier to comb. For rough, fragile lengths, those qualities matter, the aim is hair that is easier to handle and moves more beautifully.
Shu Uemura sources its rice extract from Hyogo, a prefecture in Japan’s Kansai region that is home to Kobe and a celebrated culture of rice growing and sake making.
Developed for fragile, sensitised lengths, the Leave-In Mask combines conditioning Japanese rice extract with a tetrapeptide a short chain of four amino acids, the building blocks of proteins such as keratin. The complete formula helps reinforce damaged hair, bringing softness and shine to the lengths while providing heat protection during styling.
WHEN BEAUTIFUL COLOUR NEEDS EXTRA CARE
A fresh colour can change how you feel. Repeated lightening, overlapping chemical services and years of styling can also change how your hair behaves. Add frequent heat, brushing and sunlight, and older lengths may need more attention than the newer hair nearer your roots.
Each strand has an outer cuticle, made of overlapping layers, around a protein-rich interior called the cortex, which contributes much of its strength. Bleaching and other chemical processes can affect both. When the surface becomes more worn, hair can feel rougher, tangle more readily and lose its gloss, more compromised lengths can become prone to breakage.
Repair care helps by conditioning the fibre, improving smoothness and making delicate lengths easier to manage. A leave-in also puts care at the styling stage, when brushing and heat place fresh demands on the hair. It complements a thoughtful colour plan, gentle handling and regular trims.
From a delicate soft blonde to a dimensional brunette, the shade itself does not decide your routine. Your hair’s history and present condition do. We consider both when planning balayage or face-framing lightness and the care to take home.
CARE FOR A LIVED-IN BLONDE
A fuller blonde result can still have a beautifully soft grow-out. The lightened lengths may need more conditioning than the newer hair nearer the roots, even when the overall look feels effortless. Targeted care gives those sensitised sections attention as part of your regular routine, before they become the only thing you notice about your hair.
The leave-in format suits that wish for simplicity. Apply a small amount to towel-dried, sensitised mid-lengths and ends, leave it in and style. This step adds no extra waiting time or rinse-out stage. On non-wash days, a little can also be smoothed through dry ends when they need attention.
WHAT MAKES THE ULTIMATE RESET LEAVE-IN MASK DIFFERENT?

The new 90ml Ultimate Reset Leave-In Mask is a treatment for very damaged hair that stays in after washing. Its cream-to-oil texture brings softness and smoothness to the lengths, with heat protection up to 230°C and shine for up to 72 hours.
That makes it particularly useful for someone who conditions carefully in the shower, then wants to carry that care through blow-drying and styling. Unlike the rinse-out Ultimate Reset Masque which cares for damaged hair at different stages this is your intensive conditioning treatment after shampooing, leave it on for five to ten minutes, then rinse thoroughly to reveal softer, more manageable lengths.
The Leave-In Mask has a lightweight cream-to-oil texture designed to stay on the hair, bringing repair care, shine and heat protection into your styling routine. It can also be applied sparingly to dry ends between washes.
Fine, heavily highlighted hair can need this kind of care just as much as a thick, over-processed hair. Start with a small amount through the areas that need it, keeping the roots light. Longer or denser hair may need sectioning for even distribution.
FOR THOSE WHO LOVED THE ULTIMATE RESET DUO SERUM
Ultimate Reset Duo Serum was one of our best-selling Shu Uemura products at Paul Edmonds London, a leave-in must-have for clients caring for damaged, colour-sensitised lengths. For those who loved it, the new Ultimate Reset Leave-In Mask is now our recommendation for that treatment step. With a different formula and a lightweight cream-to-oil texture, it continues the focus on care that stays with your hair between appointments.
ULTIMATE RESET OR IZUMI TONIC: WHICH SUITS YOUR HAIR?
Both ranges draw on rice, but they address different priorities. The most useful starting point is the condition of your lengths and what you want your routine to do.
Choose Ultimate Reset for very damaged, over-processed lengths
If your main concern is the aftermath of bleaching, repeated colour or chemical processing, Ultimate Reset is the more focused choice. Think persistent roughness, difficult detangling and fragile ends that need substantial conditioning care. It is suitable across hair types; adjust the amount and richness of the routine to your density.
Choose Izumi Tonic when fragile hair needs strength and a fuller feel
Izumi Tonic, inspired by the Japanese tradition of bathing hair in rice water, is a strengthening and thickening range for fragile hair. It is particularly relevant to fine or medium hair when breakage is a concern and you want the lengths to feel stronger and thicker.
There is overlap. Fine hair that has been heavily bleached may need Ultimate Reset because the level of damage is the priority. Hair that is finer and fragile, with less severe processing damage, may be better suited to Izumi Tonic. At your appointment, at our Paul Edmonds London salons we can help you judge that balance before you buy, coupled with the full backwash experience with complementary rinse out masque, to lead you into your ongoing maintenance routine.
BUILD YOUR ULTIMATE RESET ROUTINE AROUND YOUR HAIR
You can introduce the new Leave-In Mask to a washing routine you already enjoy, so you don’t have to give up on Urban Moisture or Muroto Volume if hydration and volume are still your priority, Shu Uemura’s Art of Layering different products bespoke to you, is ostensibly what the brand is all about.
A simple pairing: shampoo and leave-in
Cleanse with Ultimate Reset Shampoo, rinse, then apply the Leave-In Mask to towel-dried mid-lengths and ends. Leave it in and style. This is a straightforward introduction to the range.
Richer wash-day care: add the rinse-out Masque
When your hair needs more conditioning, follow shampoo with the Ultimate Reset Masque. Leave for five to ten minutes, then rinse thoroughly. Gently towel-dry before applying the new leave-in. The rinse-out mask provides the wash-day conditioning step; the leave-in continues the care before styling.
Moisture care with targeted repair
If dryness is your main concern but lightening has left certain sections fragile, keep Urban Moisture Shampoo and Urban Moisture Conditioner for hydrating wash-day care. Rinse the conditioner thoroughly, gently towel-dry, then apply a small amount of Ultimate Reset Leave-In Mask to the sensitised mid-lengths and ends. Leave it in and style. This pairing gives your hair moisture-focused care, with targeted repair care where the lengths need it.
A finishing touch, if your ends need it
The Ultimate Reset Extreme Repair Oil Concentrate is an optional choice for extra polish. Assess the finish first, then use a little where it improves the result. You do not need every product in the range to create a well-considered routine.
CONDITION COMES FIRST AT PAUL EDMONDS LONDON
At our Battersea Power Station salon, care at the backwash is part of creating beautiful hair. A Shu Uemura mask, selected to suit your hair’s needs, is included complimentary within our backwash service. That moment is an opportunity to assess the lengths, give them appropriate conditioning and explain what will help between visits.
For very damaged hair, that conversation may lead to Ultimate Reset. Another client may need a different Shu Uemura mask or a more targeted salon treatment, which we will discuss with you. We consider condition when planning colour, choosing a finish and recommending home care. The aim is hair that feels as beautiful as it looks.
As an authorised Shu Uemura retailer and a working London salon, we connect the products you take home with the hair we care for in the chair. Book an appointment to discuss your colour and condition, or shop the new Leave-In Mask and begin with the step your lengths need.
YOUR ULTIMATE RESET QUESTIONS ANSWERED
Who is Shu Uemura Ultimate Reset Leave-In Mask for?
It is designed for very damaged hair, including lengths weakened by bleaching, colouring and chemical processing. Hair can be fine, medium or thick; the level of damage and the amount of conditioning needed should guide your routine. A lived-in blonde with sensitised, lightened sections can also benefit from targeted care rather than changing the whole washing routine.
What is Hyogo rice, and why is it in Ultimate Reset?
Hyogo is the Japanese prefecture where Shu Uemura sources its rice extract. The extract is valued for its B vitamins, vitamin E, minerals and antioxidant profile. In the new leave-in, hydrolysed rice extract has a conditioning role, helping hair feel softer, more supple and easier to comb as part of the complete formula.
Is Ultimate Reset the same as Izumi Tonic?
No. Ultimate Reset focuses on very damaged, over-processed hair. Izumi Tonic is a strengthening and thickening range for fragile hair, particularly fine to medium textures. Fine, heavily bleached hair may still be better suited to Ultimate Reset.
Do I rinse out the Leave-In Mask or use conditioner first?
Leave the new mask in. Apply it after shampooing to towel-dried hair. A specific conditioner is not required. If you use a rinse-out conditioner or the separate Ultimate Reset Masque, rinse that away completely before towel-drying and applying the leave-in.
Can I pair Ultimate Reset Leave-In Mask with Urban Moisture?
Yes. If dryness is your main concern and some lightened sections feel fragile, use Urban Moisture for your wash and rinse-out conditioning steps. Rinse thoroughly, towel-dry, then apply a small amount of the Leave-In Mask to the sensitised lengths and ends. Leave it in before styling.
Can I use it on dry hair, and does it protect against heat?
Yes, use a small amount on dry lengths and ends between washes as needed. The formula provides heat protection up to 230°C. Use it before styling and choose an appropriate tool temperature for your hair.
Can a repair mask permanently mend split ends?
Conditioning can improve how damaged ends look and feel and make them easier to handle. Trimming removes the split section. At your appointment, we can advise on the balance of cutting, treatment and home care.
Are Shu Uemura masks complimentary in salon treatment at Paul Edmonds London?
Yes. A Shu Uemura mask selected for your hair is complimentary within our salon backwash service. Separate specialist treatments are discussed and priced individually where appropriate. Book a consultation with one of our team of experts to find what is right for you.
