Mielle Rosemary Mint Strengthening Hair Masque 340g

Mielle Rosemary Mint Strengthening Hair Masque 340g — Complete Product Guide

Product Overview

Mielle Rosemary Mint Strengthening Hair Masque is a biotin-infused, intensive deep conditioning hair masque from Mielle Organics — the award-winning Black-owned US haircare brand founded by Monique Rodriguez, built on the belief that healthy hair starts with nutrient-rich, intentionally formulated ingredients. Designed as the natural complement to the Rosemary Mint Strengthening Shampoo, this masque delivers the same rosemary-mint-biotin philosophy in a deeply concentrated, rich conditioning format that penetrates the hair shaft to restore moisture, rebuild strength, and revive dull, damaged strands. The formula combines a 10-Oil Nourishing Complex, a 7-Herb Botanical Blend, Shea Butter, Aloe Vera, Biotin, and Carnauba Wax into a luxurious intensive treatment — suitable for all hair types, with particular benefit for textured, curly, coily (3A–4C), chemically treated, braided, and heat-styled hair. Made with certified organic ingredients. Leave-in time: 15–20 minutes. Made in USA.

Biotin + Rosemary — The Core Strengthening System

Biotin (Vitamin B7) is the formula’s primary strengthening active. As a critical coenzyme in keratin biosynthesis, Biotin supports the structural integrity of the hair shaft from the inside out — helping to reduce breakage, increase strand thickness, and promote stronger, more resilient hair over time with consistent use. The masque delivers Biotin in a deep-conditioning base that allows prolonged contact with the hair shaft during the 15–20 minute treatment window, maximising nutrient absorption. The dual-form Rosemary system — Rosmarinus Officinalis Leaf Oil (1,8-Cineole; scalp microcirculation stimulant and 5-alpha reductase DHT inhibitor) combined with Rosmarinus Officinalis Leaves Extract (Rosmarinic Acid + carnosic acid polyphenols; anti-inflammatory scalp antioxidant) — provides layered scalp and follicle support that works throughout the leave-in treatment period.

Peppermint Oil — Scalp Activation During Treatment

Mentha Piperita (Peppermint) Oil delivers the formula’s characteristic scalp-tingling sensation — a signal of active vasodilation at the scalp surface. Menthol’s activation of TRPM8 cold receptors triggers increased blood flow to the scalp, delivering oxygen and nutrients to hair follicles precisely during the treatment window. This makes the masque’s leave-in period doubly effective: the oils and actives are penetrating the hair shaft while peppermint is simultaneously stimulating the scalp environment. Its antimicrobial activity also helps maintain a balanced, healthy scalp during use.

10-Oil Nourishing Complex — Deep Moisture & Repair

The masque’s most distinctive feature is its exceptionally rich multi-oil system, delivering diverse fatty acid profiles for comprehensive hair nourishment. Orbignya Oleifera (Babassu) Seed Oil* (Certified Organic) is a lightweight tropical oil that penetrates deeply without heaviness — ideal for low-porosity and fine-textured hair. Cocos Nucifera (Coconut) Oil* (Certified Organic) is the most scientifically proven oil for hair shaft penetration — its small molecular size and high affinity for hair proteins allows it to permeate the cortex and significantly reduce protein loss, the primary driver of breakage. Zingiber Officinale (Ginger) Root Oil* (Certified Organic), rich in Gingerols, stimulates scalp circulation and reduces inflammation during the treatment period.

Macadamia Integrifolia Seed Oil — exceptionally rich in Palmitoleic Acid (Omega-7), a fatty acid that mirrors the hair shaft’s natural lipids — is one of the most effective oils for restoring elasticity to brittle, chemically treated hair. Simmondsia Chinensis (Jojoba) Seed Oil, a liquid wax ester that mirrors scalp sebum, forms a flexible cuticle-sealing film that locks in moisture and controls frizz. Prunus Amygdalus Dulcis (Sweet Almond) Oil softens and adds shine; Sesamum Indicum (Sesame) Seed Oil provides Sesamol antioxidant protection against UV and environmental damage. Ricinus Communis (Castor) Seed Oil seals moisture into ends with its unique Ricinoleic Acid composition. Olea Europaea (Olive) Fruit Oil delivers deep conditioning via squalene and oleic acid, while Helianthus Annuus (Sunflower) Seed Oil provides a lightweight Linoleic Acid emollient base that keeps the formula from feeling heavy.

Shea Butter & Carnauba Wax — Sealing & Shine System

Butyrospermum Parkii (Shea) Butter acts as the formula’s primary moisture-sealing occlusive — creating a protective lipid barrier over the hair shaft that locks in all the moisture delivered by the oils and humectants during the treatment period. Rich in stearic acid, oleic acid, and triterpenes, Shea Butter also provides anti-inflammatory scalp benefits and long-lasting post-rinse softness. Copernicia Cerifera (Carnauba) Wax — the hardest natural wax — contributes a brilliant glass-like shine and a light protective coat to the cuticle surface, helping hair reflect light and appear healthier and more lustrous after each treatment.

Aloe Vera & Conditioning Base

Aloe Barbadensis Leaf Juice (Decolorized) provides lightweight hydration via Acemannan (Aloe’s signature polysaccharide), scalp anti-inflammatory relief, and detangling slip that improves application. The conditioning emulsion base is built on Behentrimonium Methosulfate + Cetearyl Alcohol — a premium mild cationic conditioning system that deposits a substantive film on the hair shaft, dramatically improving detangling, reducing friction-induced breakage, and leaving hair silky-smooth after rinsing. Cetrimonium Chloride adds further cationic conditioning and antistatic protection. Panthenol (Vitamin B5) penetrates the hair cortex to increase internal water content and improve flexibility. Phytantriol seals the cuticle flat, reduces frizz, and provides long-lasting moisture retention between washes. Tocopheryl Acetate (Vitamin E) neutralises free radicals from UV exposure and heat styling that cause oxidative damage to hair proteins.

7-Botanical Herb Complex — Extended-Contact Actives

Shared with the Strengthening Shampoo, the masque’s botanical complex works with maximum efficacy during the extended 15–20 minute leave-in window. Equisetum Arvense (Horsetail Grass) Extract supplies bioavailable silica to strengthen keratin cross-links within the hair shaft. Lawsonia Inermis (Henna) Extract binds Lawsone to damaged cuticle sites, sealing and fortifying weakened strands. Anthemis Nobilis (Chamomile) Extract soothes scalp inflammation and imparts natural shine. Symphytum Officinale (Comfrey) Extract delivers Allantoin-rich cell regeneration and scalp healing. Humulus Lupulus (Hops) Extract stimulates follicle growth activity and balances the scalp environment. Urtica Dioica (Nettle) Extract inhibits DHT and delivers iron, silica, and B-vitamins directly to follicles. Honey seals in moisture, enhances shine, and provides antioxidant and mild antimicrobial scalp protection — all benefiting from the extended contact time unique to a masque format.
