Skin-lightening is a multi-billion-dollar industry and impacts many women, and men, around the world. Within the African context, women in Nigeria use skin-whitening products the most: according to the World Health Organization 77% of women use them regularly. The situation is so bad that Nigeria's National Agency for Food and Drug Administration and Control (Nafdac) declared a state of emergency in 2023.

The BBC’s Madina Maishanu has been speaking to a mother who has used skin-whitening products on all six of her children. Madina shares her story, and talks us through the cultural context of why people use these products. We also hear from aesthetician Zainab Bashir about the risks involved with skin-bleaching.

Hundreds of thousands of students in Nigeria have been told they can retake their JAMB university entrance exam. That’s after nearly 80 per cent of them failed the test in March amid power cuts and computer glitches during the exams. The low pass rate sparked a national outcry, especially after the Minister of Education initially claimed it was caused by students cheating. The Joint Admissions and Matriculation Board has now apologised - but what does the incident say about Nigeria’s digital infrastructure?

The BBC’s Madina Maishanu explains what caused the technical issues, and why the exam board has now decided to allow retakes. We also hear from students across Nigeria about the impact the glitches have had on their hopes of getting into university.

You might have seen videos on TikTok of guys with shaved heads and black sweatbands walking round Turkish airports, or sitting on planes on the way home. Turkey is becoming one of the most popular destinations to get a hair transplant. Turkish officials estimate the hair transplant market was worth $1billion in 2024. People travel there from all around the world, but especially the US and Europe, because it’s so much cheaper than getting it done in their home country.

Christopher Mizzoni, 22 (@chrishairjourney), travelled to Turkey in 2024 to get the first of two planned hair transplants. He explains what it was like and what difference it’s made to him. Özge Özdemir from BBC Turkish explains why prices are so much lower in Turkey than other countries and sets out some concerns about the industry.

And Chris D’Souza, a hair transplant surgeon and President of the British Association of Hair Restoration Surgery tells us what the procedure involves.
