📋 Product Description
The Lover’s Hair Salon Colouring Shampoo #4.5 Chestnut Brown is an oxidative hair colourant in shampoo format — a two-part system comprising a Colouring Shampoo and a Developer that are mixed and applied together to deposit a warm, permanent chestnut brown colour on the hair. The shampoo application format makes professional oxidative colouring more intuitive and accessible for at-home use.
The colouring system uses a combination of oxidative dye intermediates — p-Phenylenediamine (PPD), p-Aminophenol, m-Aminophenol, and 4-Amino-2-hydroxytoluene — activated by the hydrogen peroxide Developer to create permanent colour molecules inside the hair shaft. 4-Amino-2-hydroxytoluene is an oxidative dye coupler that contributes warm reddish-chestnut tones to the developed colour result, distinguishing the #4.5 Chestnut Brown shade from a standard neutral brown. Ethanolamine acts as an alkaline agent to open the hair cuticle, and Sodium sulfite protects the colour chemistry during processing. Thioglycolic acid supports the formula stability as a reducing agent.
The conditioning botanical layer includes Henna (Lawsonia inermis) leaf extract, Hydrolyzed Silk, Hydrolyzed Soy Protein, Aloe barbadensis leaf extract, Panax Ginseng Root Extract, Centaurea cyanus flower water, and Lavandula angustifolia flower water — alongside a four-oil blend of Avocado, Jojoba, Camellia Japonica Seed, and Sweet Almond oils — to support the appearance of hair condition and softness through the colour process.
The Korean herbal complex — Eclipta prostrata, Rheum undulatum Root/Stalk/Stem, Vitex trifolia fruit, Angelica dahurica Root, and Angelica gigas Root — together with Hydrogenated Lecithin and Cocoyl glutamic acid, adds a distinctly premium, botanically grounded character rooted in Korean traditional hair care to the Lover’s Hair Salon Colouring Shampoo range.

💧 How to Use
- ● Step 1 — Mandatory 48-hour patch test (every application): Mix a small amount of Colouring Shampoo with a small amount of Developer. Apply to a small area of skin on the inner elbow or behind the ear. Leave uncovered for 30 minutes, then wipe off. Wait 48 hours and check the area. If any redness, itching, swelling, or irritation occurs, do not use this product and consult a physician.
- ● Step 2 — Prepare: Wear the gloves provided. Do not use on wet or freshly washed hair. Apply a barrier cream around the hairline, ears, and neck to prevent staining.
- ● Step 3 — Mix: Combine the Colouring Shampoo and Developer in the ratio specified on the product packaging. Mix thoroughly until an even consistency is achieved.
- ● Step 4 — Apply: Apply the mixed colour evenly through the hair from roots to ends, working quickly and thoroughly to ensure even coverage. Avoid contact with eyes, ears, and skin beyond the hairline.
- ● Step 5 — Develop: Leave on for the development time specified on the product packaging. Do not exceed the recommended time.
- ● Step 6 — Rinse: Rinse thoroughly with warm water until the water runs clear. Shampoo and condition the hair as normal after rinsing.
- ● Caution: For external use on scalp hair only. Do not use on eyebrows or eyelashes — risk of blindness. Avoid contact with eyes — if contact occurs, rinse immediately with water and seek medical attention if irritation persists. Not for use on persons under 16 years of age. Not for use on hair that has been relaxed with a thioglycolate product within the past 3 months. If you have previously reacted to hair colour or black henna tattoos, do not use this product.

❓ Frequently Asked Questions
Why is a 48-hour patch test required before every use?
This product contains p-Phenylenediamine (PPD) and other oxidative dye intermediates that are known skin sensitisers. Sensitivity can develop over time, even in people who have used hair colour before without any reaction. A 48-hour patch test before every application is a mandatory safety requirement — not optional. If you react, do not use the product and consult a doctor.
What gives Shade #4.5 its chestnut warmth?
The warm, reddish-chestnut depth of Shade #4.5 comes from 4-Amino-2-hydroxytoluene, an oxidative dye coupler that contributes warm red-brown tones to the developed colour result. This is what distinguishes #4.5 Chestnut Brown from a standard neutral brown shade like #5.
Is this a permanent hair colour?
Yes. This is an oxidative (permanent) hair colourant. The dye intermediates penetrate the hair shaft and develop permanent colour molecules that will not wash out. The colour will fade gradually with repeated washing over time but cannot be removed by shampooing alone.
What does the Henna extract do in this product?
The Henna (Lawsonia inermis) leaf extract is included as a botanical conditioning ingredient — not as the primary colourant. The permanent chestnut brown colour is delivered by the oxidative dye intermediates activated by the Developer. The Henna extract contributes a traditional botanical hair care character and conditioning association to the formula.
Can I use this product if I have previously used black henna tattoos?
No — if you have ever had a black henna (PPD) temporary tattoo, you may have developed a sensitivity to PPD. Using this product could trigger a severe allergic reaction. Do not use this product if you have had a black henna tattoo, even if you did not react at the time.
Can I use this on eyebrows or eyelashes?
No. This product must not be used on eyebrows or eyelashes. Use near the eyes risks serious injury including blindness. It is formulated for scalp hair only.
Is this product suitable for under-16s?
No. This product is not intended for use by persons under the age of 16.
How does #4.5 Chestnut Brown compare to #5 Brown?
Shade #4.5 Chestnut Brown is slightly darker than #5 Brown and has a warmer, reddish-chestnut tone due to the inclusion of 4-Amino-2-hydroxytoluene as an additional dye coupler. If you prefer a cooler, more neutral brown, #5 Brown may be the better choice. If you prefer warmth and depth with a reddish-chestnut quality, #4.5 is the recommended shade.
Is this product made in Korea?
Yes. This product is manufactured in Korea by Lover’s Hair Salon and distributed in Australia by First One Australia / Ausco Inc.
