The answer lies in how your scalp microbiome actually works.

Your scalp is home to a complex ecosystem of microorganisms – mainly bacteria and fungi – that live on your skin’s surface and help protect it. When this microbiome becomes imbalanced (often due to stress, diet, product overuse, or harsh shampoos), bad microbes like Malassezia yeast can overgrow, leading to inflammation, oiliness, and visible dandruff.

Resetting the microbiome isn’t instant. Just like restoring healthy gut flora, it takes time to:

Suppress the overgrowth of harmful microbes (especially Malassezia)
Reduce buildup and excess oil that feeds them
Support the good bacteria with microbiome-friendly products
Allow the scalp’s acid mantle (natural pH barrier) to stabilise

This natural renewal cycle of the scalp – including skin cell turnover and microbiome adaptation – takes roughly 21 days. That’s why the Victory Serums program includes a 3-week Reset phase using our Dandruff-Control Intensive Scalp Serum and Shampoo in a structured sequence. It's not just about clearing flakes – it's about creating an environment where dandruff can’t thrive long term.

By sticking with the process for 21 days, you’re giving your scalp the time it needs to heal, rebalance, and shift into a healthier, low-maintenance state – without relying on daily-use dandruff products.

Shortcuts don’t work with microbiome recovery – but a guided 21-day reset does.
