Frequently Asked Questions
Can I use argan oil-based heat protectants on synthetic wigs?
Yes, but cautiously. Lightweight argan treatments can help detangle and add shine to many higher-quality synthetics, but avoid applying near the wig cap and test a small strand first. Always check the wig manufacturer's care instructions before applying oils and avoid high heat on synthetic fibers.
Will these products make my extensions greasy in humid weather?
They’re formulated to be fast-absorbing and non-sticky, but showing grease depends on hair density and amount used. Apply a small amount to lengths and ends, avoid the roots, and increase sparingly if you have thicker extensions; fine hair may need less product.
How do I apply a heat protectant to avoid residue and stickiness?
Dispense a small amount into your palms or spray from a distance, work through mid-lengths to ends, and comb or finger-detangle. Allow leave-in oils to absorb for a minute before heat styling, and only reapply lightly between washes to prevent buildup.
