Strong Rebonding for Healthy, Normal Hair

The Shiseido Crystallizing Straightener H1 (1H Strong) is a powerful formula designed for healthy, normal to slightly sensitized hair. It delivers long-lasting, salon-quality straightening without the extreme intensity of the EX1 formula. If your client’s hair is healthy but resistant—frizzy, wavy, or moderately curly—this is the ideal strength to use.

Paired with the Neutralizer Cream, the H1 system locks in perfectly straight, sleek, and glossy results that last for months.

Who Is This For?

• ✅ Healthy, virgin hair that has never been chemically treated.
• ✅ Normal to slightly sensitized hair that needs strong but not extreme straightening.

How to Use (Professional Protocol)

Step 1: H1 (1H) Hair Softener

1. Apply the H1 cream from mid-lengths to ends. Keep 1-2 cm away from the scalp.
2. Process for 10-20 minutes at room temperature (up to 25 minutes for resistant hair).
3. Perform a Stretch Test: pull 2-3 strands. If it stretches to 1.5x its original length and rebounds slowly, it’s ready.
4. Rinse thoroughly with warm water. Blow-dry 100%.
5. Use a flat iron at 180°C (356°F), passing 4-5 times per section.

Step 2: Neutralizer Cream

1. Apply evenly from roots to ends.
2. Use a wide-tooth comb to distribute and keep hair straight.
3. Leave on for 20-30 minutes.
4. Rinse thoroughly. No shampoo for 48 hours.

⚠️ Safety Warnings

• For professional use or experienced DIYers only.
• Do not exceed 180°C when flat ironing.
• Avoid contact with eyes and scalp.
