This is the product I add to almost every client’s routine — not because it’s expensive or complicated, but because it’s the simplest way to extend the work your shampoo and conditioner have already done. A leave-in mist. No rinsing. Ten seconds on damp hair and you’re done.
What it does is deceptively simple: hydrolyzed keratin deposits on the hair cuticle and penetrates into the cortex, forming a protective film that strengthens and repairs at the molecular level. Red algae — a marine extract called Furcellaria lumbricalis — forms a lightweight protective barrier that shields against heat, environmental damage, and the daily friction of brushing and styling. Lactic acid gently smooths the cuticle, which is why your hair feels immediately easier to comb through. And geranium flower oil adds a subtle floral note that lifts the fragrance into something you actually notice.
In my practice in Dublin and London, this is the Essential I recommend most often. It appears in five of our seven Edits because it works with everything — the Everyday Healthy Hair routine, the GLP-1 Hair Support protocol, the Hormonal Hair Support programme, even the Hollywood special-occasion routine. It’s the universal finishing step. The one product that makes every other product in your routine perform better. 100ml lasts longer than you’d expect because you’re misting, not pouring.
This is for you if
- You want to extend the benefits of your shampoo and conditioner between washes
- Your hair tangles easily and you want something that detangles without weight
- You use heat tools and want daily protection without silicone
- Your hair feels dull or flat between wash days
- You want a finishing step that takes ten seconds and makes a visible difference
- You already use an HHE shampoo and conditioner and want to complete your routine
Consider instead if
- Your hair needs deep weekly repair rather than daily protection — our Intensive Rescue Hair Mask delivers the intensive nourishment this mist isn’t designed to replace
- You want a pre-shampoo oil treatment for scalp and root health — our Rosemary Strength Oil addresses the foundation rather than the finish
- Your primary concern is your scalp rather than your hair — start with the Sensitive Scalp Shampoo and build from there
- You haven’t found the right shampoo and conditioner yet — this mist works best as the finishing layer on a routine that’s already right, not as a fix for one that isn’t
What’s Inside
A concentrated 17-ingredient formula — every ingredient earns its place. No fillers, no silicones, no wax. Just targeted actives in a lightweight mist.
Red Algae
FURCELLARIA LUMBRICALIS
A Baltic Sea marine extract that forms a lightweight protective film around the hair shaft. Shields against heat damage, environmental stress, and the friction of daily styling — without the heaviness of silicone. The invisible armour in this formula.
Hydrolyzed Keratin
STRUCTURAL PROTEIN
At INCI position #5 in a short formula, this is a genuinely prominent concentration. The same protein your hair is made from, broken down small enough to penetrate and repair. Strengthens, improves elasticity, and reduces breakage — working continuously between washes.
Lactic Acid
CUTICLE SMOOTHER
A gentle alpha hydroxy acid that smooths the hair cuticle — the outermost layer of each strand. A smooth cuticle reflects light better (that’s where shine comes from), reduces tangling, and helps hair retain the moisture your conditioner just delivered. The reason this mist makes your hair feel immediately different.
Geranium
PELARGONIUM GRAVEOLENS
A flower oil with gentle conditioning properties and a subtle floral character that lifts the overall fragrance. Balances oil production on the scalp and helps maintain a fresh, healthy feel between washes. The ingredient that makes this mist feel like more than a functional spray.

Your Ritual
After washing and conditioning, gently towel-dry your hair. Hold the mist 15-20cm from your head and spray evenly through mid-lengths and ends. No rinsing — just leave it in. Comb through gently if needed. That’s it.
On non-wash days, use it as a refresher. A few sprays on dry hair revives shine, tames flyaways, and brings back the softness from your last wash. This is particularly useful if you follow Clare’s four-times-a-week wash recommendation — the mist bridges the gap on the days between.
You can also spray it before heat styling for lightweight protection. The red algae film helps shield against heat damage without leaving residue or weighing hair down the way silicone sprays do. It’s not a dedicated heat protectant — but it gives your hair a genuine advantage.
100ml sounds small, but a mist bottle delivers in fine sprays. Most clients get six to eight weeks from a bottle, even with daily use.
The Experience
Fresh and aquatic with delicate sweet floral petals, settling into something softly fruity with a warm vanilla undertone. Light enough to layer over any shampoo and conditioner fragrance without competing. It’s the finishing note — the thing that makes your hair smell considered even on day three.
Works with Every Routine
This mist is the universal finishing step across the entire HHE range. It works with every shampoo and conditioner combination — just add it after conditioning and between washes.
Pair with your Routine
Moisturising Shampoo & Conditioner
The daily foundation. Moisturising Shampoo and Conditioner cleanse and nourish, then this mist seals and protects. Clare's most recommended combination.
Volume Boost Shampoo & Conditioner
For fuller, thicker-feeling hair. The Volume Boost duo stimulates and strengthens, then this mist adds shine and daily protection without weighing down the volume.
Colour Care Shampoo & Fresh Conditioner
For colour-treated hair that needs daily defence. The Colour Care Shampoo protects the colour, then this mist adds shine and smoothness that make your colour look its best.
Enhance with Essentials
Rosemary Strength Oil
Weekly deep nourishment for scalp and hair. Apply before shampooing, leave for 15 minutes, then wash as normal. The mist after masking seals and extends the treatment.
Intensive Rescue Hair Mask
Once a week, swap your conditioner for this intensive mask. The mist afterwards acts as the finishing seal — locking in the deeper nourishment the mask has delivered.

Red algae forms a lightweight protective film against heat, friction, and environmental damage.
Use on damp hair after conditioning and on dry hair between wash days — the universal finishing step.
FAQ
Yes — that’s one of its primary uses. A few sprays on dry hair revives shine, tames flyaways, and brings back softness between wash days. The keratin and red algae continue to protect and strengthen every time you apply. Particularly useful on the days between washes if you follow Clare’s four-times-a-week recommendation.
No. This mist is a leave-in finishing step, not a replacement for rinse-out conditioner. Your conditioner delivers deep moisture and repair during the wash; this mist extends and protects that work throughout the day. Use both — conditioner in the shower, mist after.
The red algae extract forms a lightweight protective film that helps shield against heat damage, and the hydrolyzed keratin has been shown to maintain hair tensile strength under environmental stress. It provides genuine protection before heat styling, though it is not formulated as a dedicated high-heat protectant. For everyday blow-drying and moderate styling, it offers meaningful defence.
Yes. The Shine Leave-In Hair Mist is COSMOS Natural certified by ECOCERT Greenlife, with 99% natural origin ingredients and only 17 total ingredients. This certification applies to this specific product — not all products in the Hair Health Essentials range carry COSMOS Natural certification.
Any HHE shampoo and conditioner combination. This mist is the universal finishing step — it appears in five of seven Hair Health Essentials Edits. The most popular pairing is the Moisturising Shampoo and Moisturising Conditioner. For volume, pair with the Volume Boost Shampoo and Conditioner. For colour-treated hair, pair with the Colour Care Shampoo and Fresh Conditioner.
Most clients get six to eight weeks from a bottle, even with daily use. The mist bottle delivers a fine spray — a few seconds of misting is all that’s needed per application. You’re misting, not pouring, so the product goes significantly further than the bottle size suggests.
