The White Shampoo trend took over TikTok as a humorous way for users to experiment with their appearance using nothing but soap suds. By piling thick, white shampoo or shaving cream onto their heads, creators mimic everything from historical powdered wigs to dramatic 'glow-up' reveals or self-deprecating jokes about receding hair lines. It gained massive traction due to its low-cost execution and the satisfying visual aesthetic of the thick foam. Usually paired with ironic music, the meme highlights the internet's love for physical comedy and the relatable struggle of maintaining a hairstyle or hiding a bad hair day.
