Viviscal Hair Thickening Serum
James recommends this “lightweight leave-in treatment” from Viviscal. “[It’s] fortified with marine collagen and seaweed extract along with keratin to give the hair a thicker, fuller appearance,” she says. It’s suitable for all hair types, and reviewers say it’s easy to apply and works great to reduce frizz, too.
“My hair feels thicker, looks fuller, and ‘filled in’ where I had a little patchiness from hair thinning/loss,” writes one Amazon shopper. “I was skeptical of a hair serum thinking it would make my hair look greasy, but thankfully this one absorbs great and just makes my hair look super healthy!”
