In two helmets, as it turned out,
Bo-Katan Kryze wears a deaf helmet every day, and when he removes it, he displays impeccable styling. In an interview with ComicBook, actress Katee Sackhoff discussed the meaning of her character's hairstyle.
The Mandalorian's make-up artists don't really use any special polishes or anything like that. The secret isn't in the hair, but in the helmet.
Katie notes that the series' creators have tried very hard to make Bo-Katan's hairstyle shine. Who knows. Perhaps technology will help.
Katy and the make-up artists will not wear two helmets until after the fifth episode of the third season, as Bo-Katan will display both her face and her fantastic styling.
This is an interesting article.
