How to Use (Cara Penggunaan Ala Salun)

Step 1: 1N Hair Softener (Ubat Pelembut Rambut)

Application: Apply the 1N cream evenly from the mid-lengths to the ends of the hair. Crucial: Keep the product 1-2 cm away from the scalp to avoid irritation, burns, or severe hair breakage.
Processing Time: Leave on at room temperature for 10 to 20 minutes. Perform a “Stretch Test” by gently pulling 2-3 strands of hair. If it stretches elastically to 1.5x its original length, the hair is sufficiently softened.
Rinse & Iron: Rinse thoroughly with warm water to remove all chemical residue. Blow-dry the hair 100%, then use a flat iron at 180°C (356°F) to lock the straight shape in, section by section (holding 2-3 seconds per section).

Step 2: Neutralizer 2 Cream (Ubat ‘Lock’ Lurus)

Application: Apply the Neutralizer 2 cream evenly all over the hair, from roots to ends, to lock in the newly straightened shape.
Comb & Wait: Use a wide-tooth comb to ensure even distribution and keep the hair perfectly straight. Leave the neutralizer on for 20 to 30 minutes.
Final Rinse: Rinse thoroughly with clean water. Failing to completely wash out the neutralizer can leave the hair brittle over time. Blow-dry and style!

Ingredients (Bahan-Bahan)

Neutralizer 2 Cream: Contains Water, Cetearyl Alcohol, Dimethicone, Behenyl Alcohol, Hydrogen Peroxide, and intensive conditioning agents to add weight and shine to the hair. (Note: Contains Hydrogen Peroxide).
1N Straightener: Features a medium-strength chemical softener base with ingredients like Ammonium Thioglycolate designed to gently break down the hair bonds of sensitized/colored hair without over-processing. (Note: Keep out of reach of children and avoid contact with eyes).

⚠️ Safety Warnings (Amaran Keselamatan)

For Professional Use / Experienced DIYers: Incorrect processing times or applying Step 1 directly to the scalp can cause hair to become “gummy”, snap, or cause scalp burns.
Temperature Control: Do not exceed 180°C when ironing the hair to prevent severe heat damage.
Please note: Not suitable for severely bleached or extremely damaged hair (for bleached hair, consider the 1S Softener instead).
