Christina Applegate has given fans a rare glimpse into her life following an extended hospital stay and months of limited social media activity.
The 54-year-old actress returned to Instagram on September 21 with a short video showing off her freshly coloured blonde hair. She also pointed out a new spot on her cheek, joking about the unexpected change.
The update comes as Applegate continues to live with multiple sclerosis (MS), which she publicly revealed she had been diagnosed with in 2021.
Christina Applegate Shares a Rare Instagram Update
In her latest Instagram video, Applegate appeared casually dressed as she showed followers her brighter blonde hair.
She then turned her face toward the camera, making a darker area on her cheek more noticeable.
Rather than treating the change dramatically, Applegate addressed it herself with humour. She described it as a “new weird spot” and thanked hairstylist Dave Stanwell for helping brighten her day.
She did not explain what caused the mark on her cheek. Therefore, there is no confirmed information connecting the skin change to her MS or any other medical condition.
The Update Comes After Months Away From Social Media
Applegate’s latest appearance is notable because she has been relatively quiet online during a difficult period for her health.
According to recent reports, she spent several months hospitalised in 2026 and returned home in August. The specific reason for the hospitalisation has not been publicly confirmed.
In an earlier message following the hospitalisation, Applegate thanked people for their support and said she was focusing on her health.
Her September Instagram video marks her first new video post in months, according to multiple reports.
Christina Applegate’s Multiple Sclerosis Diagnosis
Applegate publicly revealed her multiple sclerosis diagnosis in August 2021.
MS is a disease involving the central nervous system. It can affect the brain, spinal cord and nerves, and symptoms can vary significantly from person to person.
Applegate has been unusually open about the physical challenges she has experienced since her diagnosis.
During a 2024 interview with Good Morning America, she discussed difficulties with walking and explained that her symptoms had progressed while she was filming the final season of Dead to Me.
She has also credited actress Selma Blair, her former co-star in The Sweetest Thing, with encouraging her to get tested for MS.
Blair had publicly revealed her own MS diagnosis in 2018.
Applegate Has Spoken Openly About Life With MS
Rather than presenting her experience as simple or predictable, Applegate has frequently discussed the less visible parts of living with MS.
She has spoken about fatigue, mobility problems and pain, as well as the emotional impact of changes to her daily life.
Her experiences also became a major part of her memoir, You With the Sad Eyes, which was published by Little, Brown and Company in March 2026.
The memoir explores Applegate’s life and career, including the impact her MS diagnosis had on her physical abilities and everyday life.
Her Career Changed After the MS Diagnosis
Applegate’s health challenges have also affected her approach to acting.
Her most recent major television role was in Netflix’s Dead to Me, where she starred alongside Linda Cardellini.
In a 2023 interview with Vanity Fair, Applegate said she could not imagine returning to a traditional set at that point. Her comments reflected how significantly her health had changed her working life.
Despite stepping back from acting, she has continued to communicate with audiences through interviews, social media and her podcast work.
Applegate Continues to Use Humour While Discussing Her Health
One recognisable part of Applegate’s public approach to her illness has been her use of humour.
She has spoken frankly about difficult and uncomfortable experiences instead of presenting a polished version of life with MS.
That approach has also carried into her podcast MeSsy, which she co-hosts with Jamie-Lynn Sigler, another actress living with multiple sclerosis.
Their conversations have focused on the realities of living with the disease, including physical symptoms, emotional struggles and changes in everyday life.
Her New Hair Offers a Lighter Moment
Against that broader health journey, Applegate’s latest Instagram video was relatively simple.
There was no major announcement. Instead, she showed followers a fresh hair colour, joked about the new mark on her cheek and thanked her stylist.
The light-hearted update also gave fans their first recent look at her following months of health-related challenges.
For now, Applegate has not provided additional details about the spot on her cheek. Her latest post remains a personal update rather than a medical announcement.
Christina Applegate Health Update: What We Know
Applegate continues to be open about her experience with MS, but some aspects of her current health remain private.
Her recent hospitalisation was reported to have lasted several months, although the exact cause has not been publicly confirmed. Her September 21 Instagram post focused instead on her new appearance and a message of appreciation to her followers.
It is also important not to assume that every new physical change is related to MS. Applegate has not said that her cheek spot was caused by the disease.
For that reason, the cause of the discolouration remains unknown.
