People with curly, wavy, relaxed, or frizzy hair who want to blow-dry or flat-iron it into a smooth, straight style and want some heat/humidity protection while doing so. Suitable for beginners through experienced heat-stylers. Not intended for those wanting to enhance or define their natural curl pattern (it's a straightening aid, not a curl cream), and the smoothing effect is temporary — it doesn't chemically alter curl structure.

Its value is in combining two jobs in one step — smoothing conditioning ingredients like keratin and silk amino acids sit alongside a humidity-resistant, heat-protective base, so instead of layering a separate heat protectant and finishing serum, one product handles both the protection during styling and the sleek finish afterward, while also shortening blow-dry time.

• Apply an appropriate amount evenly through damp, towel-dried hair
• Blow-dry (or air-dry) the hair, then finish with a flat iron for the desired straight style
• Intended for curly, wavy, relaxed, or frizzy hair being styled straight

Pros:

• Doubles as a heat protectant during blow-drying and flat-ironing
• Humidity-resistant formula, so straightened styles hold up longer before reverting
• Brand states it cuts blow-dry time roughly in half
• Contains keratin and silk amino acids for added smoothness and shine

Cons:

• Built specifically for straightening — won't define or enhance natural curl pattern
• Results are temporary and revert with washing or humidity exposure over time
• Contains added fragrance, which may not suit fragrance-sensitive users
