Doctor explains how you can repair hair after it's damaged by extreme bleaching

Brittle strands, severe breakage, and a spectrum of unwanted brassy hues are the telltale signs that your hair bleaching has gone wrong.

Mishaps with peroxide not only compromise hair health but can also make you regret seeking the bottle blonde look or sunkissed highlights you've always wanted. However, there is a way you can save your dry hair from any further damage.

Dr Muneeb Shah, who posts online as @dermdoctor, is a board-certified dermatologist, influencer and founder of clinically backed skin-care line Remedy. He boasts more than 18.1million followers on social media and is known for sharing his knowledge about skin and hair care online.

In a recent video, which has gained more than 101,000 likes, Dr Shah explained that the process of bleaching strips the hair of its natural oils and it was important to replenish them as soon as possible. He explained: "Bleaching hair swells the hair strand, lifts the cuticle and removes the natural oil layer of the hair.

"This can lead to breakage and frizziness if it's not repaired early. Garnier Fructis Hair Filler is an affordable option to help repair damaged hair.

"Citric acid helps to bring your hair pH back to normal and increases ionic bonding to improve hair strength and recement that lifted cuticle, Aimo dimethicone helps to condition by attaching to negatively charged hair.

"I absolutely love the hair science in this system. Derm doctor approved."

TikTok users immediately took to the comments to thank the expert for his advice after having some bleaching disasters. One user said: "So needed this… thank you!!"

Another added: "LOL I need help," while a third commented: "This shampoo is so good for tangled and shedding hair." Meanwhile, a fourth penned: "I bleached my hair 3 times and dyed it 3 times in the span of 3 days. my hairs fine now (it keeps falling out)."
