Many smoothing sprays are labeled for “All Hair Types.” Others specifically call out frizzy, curly, coarse, wavy, dry, textured, or normal hair, and may highlight needs like reducing frizz or adding manageability.
Usage varies by product: some sprays are applied to damp hair and combed through before air-drying, others are misted onto dry hair before flat-ironing, and aerosol finishing sprays are typically used 8–10 inches from the hair in short bursts over finished styles.
Smoothing sprays are sold as pump/spray bottles, aerosol spray cans, and liquid spray formulas (non-aerosol).
Some smoothing sprays advertise heat protection up to about 450°F. A few pair that heat protection with claims about longer-lasting smooth or straight finishes (examples: 48–72 hours).
Smoothing sprays are sold in travel and small sizes (around 1.5 oz), mid-size bottles (about 5–6 fl oz), and larger aerosol cans (around 8–10 oz)—examples include 1.5 oz, 5 fl oz, 5.5 oz, 6 fl oz, 8 fl oz, 8.1 fl oz, and 10 oz.
