Save precious time and shelf space with this hybrid hair treatment that does triple-duty as a conditioning, finishing, and styling product. Ultralight but intensely moisturizing, the herbal-scented Vanishing Oil by Privé ($36) features a luxurious blend of argan, maracuja, and Brazil nut oils that work immediately to soften, tame flyaways, and add shine when applied to damp or dry hair. "The best part of it is that it won't weigh down hair," says creator and founder of Privé salons, Laurent Dufourg. It's particularly great for adding that bit of shine to a finished, swingy ponytail. But the formula also penetrates deep into the hair’s shaft to promote growth and transform its health and luster when used regularly.
