Lifestyle Style Chrissy Teigen Shows 'New Brow Hairs' Growing in Following Cosmetic Transplant Procedure The star underwent an eyebrow transplant to create fuller arches after years of overplucking By Kaitlyn Frey Kaitlyn Frey Instagram Twitter Assistant Style & Beauty Editor, PEOPLE People Editorial Guidelines Published on December 29, 2021 12:05 PM Share Tweet Pin Email Chrissy Teigen's updating fans on her eyebrow regrowth after getting a brow transplant last month. About a month after undergoing the cosmetic procedure, where hairs are taken from the back of a patient's head and placed on the face to create a fuller set of brows, Teigen, 36, shared an Instagram video showing off her new, bushy brows. "welcome, new brow hairs!!!!" Teigen captioned the makeup-free clip as she moved her face side-to-side to reveal her fluffy eyebrows. Teigen, who previously said she tries to "never wear makeup" if she can "avoid it" visited Dr. Jason Diamond and Dr. Jason Champagne for the transplant procedure. When she showed off her brows following the surgery in November, Teigen called the results "crazy." Adding in an Instagram clip that "they look so cool." Board-Certified Facial Plastic and Reconstructive Surgeon Dr. Paul Nassif said most candidates who come in for an eyebrow transplant typically want full, natural brows. It can be anyone from a person who plucked too many stray hairs, to someone with naturally thin arches or a person with no brow hair at all, he told PEOPLE. Chrissy Teigen/Instagram Chrissy Teigen Debuts New Eyebrows Following Transplant, Warns Teens to 'Not Pluck Them All Off' "The procedure involves taking a hair follicle from the back of the scalp and transplanting the hair gently – with the right angle, and the right curve – into the eyebrow," Dr. Nassif said. "It's important your doctor uses a light hand when you do this and with the right angle. Otherwise, the brows can come out looking too bushy and unnatural." Chrissy Teigen/Instagram New York City-based Facial Plastic Surgeon Dr. Yael Halaas said hairs are pulled from the back of the head because it's the area that "best mimics eyebrow hairs." Chrissy Teigen Got an Eyebrow Transplant – Here's What to Know About the Cosmetic Procedure "The transplanted scalp hairs will continue to grow, unlike natural eyebrow hairs that have a natural 'turn-off' switch. So the new eyebrow hairs will need to be trimmed and groomed with more frequency," Dr. Halaas told PEOPLE. While the entire eyebrow transplant can be completed in one visit, it takes time to see the full results, Dr. Nassif and Dr. Halaas said. Chrissy Teigen/Instagram "The hair follicle that is being transplanted into the eyebrow has a hair on it. But that hair will fall out and then a new one will grow in," said Dr. Nassif. "Results can be seen anywhere between six to nine months for full growth and the results are permanent."
