Dr Laura's Notes

This is for you if…

Your hair is damaged or has accumulated product buildup and you want to reset and repair in one session at a better price than buying both products separately.

Deep-cleansing detox shampoo and bond-repair mask duo to reset scalp and restore damaged hair strength and shine.

K18PEPTIDE™ (IN THE LEAVE-IN MASK): The patented bioactive peptide that bonds inside the hair strand and rebuilds broken keratin chains, restoring strength and softness.

SALICYLIC ACID AND ACTIVATED CHARCOAL (IN THE DETOX SHAMPOO): Remove product buildup and excess sebum, creating the clean baseline the K18 peptide needs to bond effectively.

BEHENTRIMONIUM CHLORIDE (IN THE LEAVE-IN MASK): Conditions and smooths the hair cuticle after the deep cleanse.

PANTHENOL (IN BOTH PRODUCTS): Maintains hydration and comfort through both the cleansing and repair steps.

RESET AND REPAIR IN ONE SESSION: The Detox Shampoo removes buildup and preps hair for the K18 Leave-In Mask, which then rebuilds damaged strands from inside in 4 minutes.
DEEP CLEANSING BEFORE TREATMENT: Salicylic acid and charcoal create the clean baseline that allows K18Peptide™ to bond most effectively.
MOLECULAR REPAIR WITHOUT RINSING: K18Peptide™ works inside the hair shaft for 4 minutes leave-in, rebuilding broken keratin chains without needing to be washed out.
WORKS ON ALL HAIR TYPES: Suitable for bleached, colour-treated, heat-styled and chemically processed hair of all textures.

Why It's Phare Approved

The Prep + Repair Duo combines the two products I'd use back to back on damaged hair: the Detox Shampoo resets the scalp and strips accumulated buildup, and the Leave-In Mask follows immediately to rebuild the strand from inside using K18Peptide™. The detox and repair sequencing is what makes the mask work best: clean hair with no residue allows the peptide to bond more effectively. If you're starting K18 or doing a periodic hair reset, this is the most efficient way to do it.

1. Apply the Detox Shampoo to wet hair, massage into scalp and lengths, leave for 2 to 3 minutes, then rinse thoroughly.
2. Towel-dry hair until damp.
3. Apply 3 to 9 pumps of the Leave-In Mask to mid-lengths and ends depending on hair length and density. Leave for 4 minutes.
4. Do not rinse. Style as normal.
Detox Shampoo: Water (Aqua), Sodium Lauroyl Methyl Isethionate, Cocamidopropyl Betaine, Charcoal Powder, Salicylic Acid, Sodium Chloride, Glycerin, Panthenol, Disodium EDTA, Phenoxyethanol, Ethylhexylglycerin, Fragrance (Parfum)

Leave-In Molecular Repair Hair Mask: Water (Aqua), Alcohol Denat., Propylene Glycol, Cetearyl Alcohol, Behentrimonium Chloride, Hydrolyzed Wheat Protein, Hydrolyzed Wheat Starch, K18Peptide™ (sh-Oligopeptide-78), Phenoxyethanol, Ethylhexylglycerin, Fragrance (Parfum)

Yes. K18Peptide™ works at the molecular level inside the hair strand and is effective on all hair types, textures and whether hair is colour-treated or natural.
No. It's a leave-in treatment. Apply to towel-dried hair, wait 4 minutes and style as normal. Rinsing it out removes the peptide before it can bond.
Use the Detox Shampoo once a week or whenever hair feels heavy or product-coated. After the detox wash, follow with the Leave-In Mask. For ongoing repair, use the mask every wash for the first 4 to 6 washes, then every 3 to 4 washes to maintain.
Yes. The ingredients in both products are considered safe during pregnancy and breastfeeding. The salicylic acid in the shampoo is at a low concentration in a rinse-off formula.
