Smooth out waves and frizz and lock in a sleek, natural-looking straight finish with ReFa STRAIGHT LOCK. Inspired by salon-popular acid-heat (“acid thermal”) treatments, this milk-type styling treatment helps refine unruly texture while keeping hair touchably soft and easy to manage. Use it with heat from a dryer or straightener to create hair that falls beautifully and feels silky from root to tip.

Product overview:
ReFa STRAIGHT LOCK is a styling product designed to repair hair from within and, when combined with the heat of a flat iron, guide wavy or frizzy hair toward a straighter, more obedient look. By blending Acid-Heat Lock ingredients with Heat Care ingredients in an original formula, it helps reduce damage while supporting a smooth, straight style.

Key benefits:
- Controls frizz and waves, helping hair sit straighter and more neatly
- Enhances straightening results when used with heat (hair dryer or straight iron)
- Helps repair and care for damage while styling
- Helps protect the style from daytime humidity and dryness
- Moisturizes while maintaining a light, smooth finish and easy slip

How it works (formula points):
- Point 1: Wave/frizz control and straight “lock”
- Formulated with key ingredients used in acid-heat treatments (Acid-Heat Lock ingredients) to help repair and condition hair while improving frizz and wave control, supporting a softer, more natural straight look that’s easier to style.

- Point 2: Damage repair and longer-lasting hold
- Heat-reactive Heat Care ingredients adhere to damaged areas to help repair them. By smoothing and tightening the cuticle, the formula helps protect hair from humidity and dryness throughout the day and helps the locked-in style last longer.

- Point 3: Moisture + lightweight feel with selected phyto oils
- Carefully selected phyto oils coat the hair to help prevent heat from escaping, making it easier to deliver ingredients throughout the hair. The oils are chosen for resistance to high temperatures and for being less affected by heat and oxidation. The formula is also designed to blend well with water, helping the Acid-Heat Lock ingredients penetrate, moisturize, and leave hair feeling smooth and silky.

Texture:

Scent:
- Fruity floral fragrance with gentle sweetness of pear and apple, plus refreshing green notes
