Your Shampoo Expires—Don’t Use It After This Date! You Won’t Believe What Happens Next! Shampoo doesn’t last forever. Even if your bottle looks perfectly fine and the label hasn’t faded, using expired shampoo can jeopardize your hair health and even risk scalp infections. What exactly happens when shampoo expires? More importantly—how can it affect your hair and scalp? Let’s uncover the shocking truth behind expired shampoo and why you should never ignore the expiration date. ### Why Shampoo Expires—The Science Behind It Shampoos are formulated with delicate chemical balances: surfactants, preservatives, fragrances, and moisturizers. Over time, exposure to light, air, temperature fluctuations, and humidity causes these ingredients to degrade. The preservatives that once kept bacteria and fungi at bay gradually lose effectiveness, making the product a potential breeding ground for microbes.
