MISE EN SCENE Hello Bubble 6N Choco Brown is a popular at-home bubble hair dye kit from South Korea, known for its easy application, natural color, and hair-friendly formula. Its core features are:

1. Bubble Formula for Easy, Even Application: The dye transforms into rich, creamy foam when mixed— the foam adheres to hair strands evenly (even hard-to-reach areas like the back of the head), eliminating uneven coloring and messy drips. No professional tools (e.g., brushes, bowls) are needed, making at-home coloring simple.
2. Natural 6N Choco Brown Shade: A soft, warm chocolate brown that is not too dark (avoids looking "blackish") or too light (avoids looking "brassy")— it enhances skin tone, adds warmth to the face, and looks natural in both indoor and outdoor light. It works well on both natural hair and previously dyed brown hair.
3. Conditioning & Damage-Minimizing Formula: Infused with hair-nourishing ingredients (e.g., argan oil, camellia oil, panthenol) that moisturize hair during coloring— they reduce dryness and frizz caused by dyeing, leaving hair soft, smooth, and glossy (not rough or straw-like).
4. Semi-Permanent to Demi-Permanent Longevity: The color lasts 4-6 weeks with proper care (using sulfate-free shampoo, avoiding excessive heat styling)— it fades gradually into a lighter warm brown, rather than harshly, so root regrowth is less noticeable.
5. Complete Kit with All Necessities: Each kit includes everything needed for coloring— 1 tube of colorant, 1 bottle of developer, 1 packet of after-color treatment (to lock in color and nourish hair), 1 pair of gloves, 1 hair cap, and 1 instruction manual (in multiple languages, including English and Chinese).

（specific ingredients subject to product packaging; core components listed below）：
Hair-Coloring Active Ingredients:
p-Phenylenediamine (PPD): A common oxidative hair dye ingredient that helps develop the 6N Choco Brown shade— it reacts with the developer to penetrate the hair cuticle and deposit color, ensuring long-lasting results. (Note: PPD may cause sensitization in some users, so a patch test is mandatory.)
Resorcinol: A coupling agent that works with PPD to adjust the tone of the brown color— it enhances the warm, chocolate-like hue and improves color stability.
m-Aminophenol: Another coupling agent that helps refine the color depth, preventing the shade from becoming too dark or brassy.
Developer (Oxidizing Agent):
Hydrogen Peroxide (3%-6% concentration): The developer that activates the colorant— it opens the hair cuticle to allow colorants to penetrate, and helps oxidize the dyes to form the final color. The low concentration (3%-6%) minimizes hair damage compared to higher-concentration developers.
Conditioning & Nourishing Ingredients:
Argan Oil: A rich moisturizing oil that penetrates the hair cuticle, replenishes lipids, and reduces dryness caused by dyeing— leaves hair soft and glossy.
Camellia Oil: A lightweight oil that forms a protective layer on hair strands, locking in moisture and preventing color fading— it also adds shine without making hair greasy.
Panthenol (Vitamin B5): Converts to pantothenic acid in hair, which strengthens hair fibers, reduces breakage, and improves hair elasticity— ideal for minimizing 染发 - related damage.
Bubble-Forming & Stabilizing Agents:
Sodium Lauryl Sulfate (SLS) / Sodium Laureth Sulfate (SLES): Surfactants that create and stabilize the foam— they help the dye mixture form a rich, long-lasting foam that adheres evenly to hair.
Cocamidopropyl Betaine: A mild surfactant that enhances foam quality and reduces irritation to the scalp and hair— it complements SLS/SLES to make the formula gentler.
Safety & Stabilizing Additives:
Disodium EDTA: A chelating agent that prevents metal ions in water from reacting with colorants— it maintains color stability and extends the dye’s shelf life.
Citric Acid: Adjusts the pH of the formula to match the scalp’s natural pH (slightly acidic), reducing scalp irritation and improving color absorption.
Fragrance: A mild, low-irritation fragrance that masks the chemical smell of dye ingredients, making the coloring process more pleasant.

Patch Test & Strand Test (24 Hours Before Coloring):
Patch Test: Apply a small amount of mixed dye to the inner elbow or behind the ear— wait 24 hours. If no redness, itching, or swelling occurs, proceed with coloring.
Strand Test: Cut a small section of hair (from the back of the head, hidden area) and dye it— check the color result and how the hair reacts (e.g., dryness) to ensure satisfaction.
Prep Hair & Tools:
Wash hair 1-2 days before coloring (oily hair helps protect the scalp from irritation; avoid using conditioner). Dry hair completely.
Wear old clothes or a hair cape to avoid dye stains. Put on the included gloves.
Mix the Dye:
Squeeze the entire tube of colorant into the bottle of developer. Close the bottle tightly and shake vigorously for 1-2 minutes until the mixture turns into a uniform foam.
Apply the Foam:
Start applying the foam to dry hair— first to the roots (1-2 cm from the scalp, avoid direct scalp contact), then spread the remaining foam to the mid-lengths and ends. Use fingers to massage the foam into hair, ensuring every strand is covered.
After full application, put on the included hair cap and let the dye sit for 20-30 minutes (adjust time based on desired color depth: longer for darker shade, shorter for lighter shade).
Rinse & Post-Treatment:
Rinse hair with lukewarm water until the water runs clear (no dye residue). Do not use shampoo.
Apply the included after-color treatment to wet hair, massage gently, and leave on for 3-5 minutes. Rinse thoroughly with lukewarm water.
Post-Coloring Care:
Dry hair gently with a towel (avoid rubbing). Use sulfate-free shampoo and conditioner to maintain color and prevent fading. Avoid excessive heat styling (e.g., straighteners, curling irons) for the first week.
