Frequently Asked Questions
Can I use leave-in sprays on human hair extensions?
Yes — most water-based leave-ins and lightweight serums are safe for human hair extensions. Use a fine mist and apply sparingly at the mid-lengths and ends, avoiding the bonded or sewn wefts if your extension type has adhesives or tape to prevent loosening. Look for heat/UV protection if you plan to style with heat.
How do I avoid a sticky or greasy finish in humidity?
Choose lightweight, non-greasy formulations and use small amounts. Spray from 8–12 inches away for an even mist, focus on mid-lengths and ends, and comb through to distribute. Avoid heavy oils and butters on humid days — they attract moisture and can lead to tangling.
Are silicones bad for extensions?
Silicones can provide excellent slip and cuticle smoothing, which helps detangle and resist frizz — useful in humidity. However, some silicones build up over time; choose water-soluble silicones or ensure your routine includes occasional clarifying cleansing if your formula uses heavier silicones.
