Look for lightweight hydrators.
Specifically hyaluronic acid, squalane, and glycerin. All of these ingredients lightly moisturize hair without creating a film or residue that can make your waves, curls, or coils look pulled out and greasy. You can also try light oils—like sunflower seed oil, grapeseed oil, jojoba oil, and argan oil—which absorb into hair fairly quickly too.
A few ingredients to avoid? Shea butter, castor oil, and mango seed butter. These don't absorb quickly, so they'll likely just leave a residue on your low-porosity hair. Trichologist Bridgette Hill also recommends avoiding protein overload on any hair type, of course, but especially for low-porosity hair that's prone to looking flat and stringy, according to a previous Cosmo article.
Opt for lightweight textures.
Instead of coating your hair in rich creams and heavy oils, choose hair products with lightweight textures, like foams, serums, and milks. These will naturally sink into your hair faster and not leave as much of a film on your strands. For this reason, testers were big fans of the Biolage Bond Therapy Conditioning Foam, the Rōz Milk Hair Serum, and Anablue Hair Serum.
