What is a scalp microbiome?

Just as our gut has live bacteria — AKA ‘microbes’— so does our scalp. With its own unique ecosystem, the scalp is host to a range of microbes (from bacteria and fungi through to environmental toxins) that live on the scalp’s surface and feed on sebum (your hair’s natural oil). A balanced scalp microbiome is one where diverse bacteria work together as a team to strengthen the skin’s surface layer and create a habitat for follicles to thrive and roots to grow into healthy Straands.

How does Straand help my hair?

Treating the skin on your head as well as you treat the skin on your face, hair has a better chance at thriving by focusing on removing product build up, grime and balancing the biome. In tending to your hair through crown care, your scalp microbiome becomes a fertile ground for hair to thrive and grow, while renewing root hydration to give hair serious gloss.

How soon will I see results?

No two Straands of hair are the same, which means no two scalp microbiomes will balance out in the same way or at the same time. As a rule of thumb, we suggest adding scalp care into your beauty routine, stat! By massaging your scalp (from the scalp to roots and strands) with The Crown Cleanse, two to three times a week (completing a two-step rinse and repeat cycle), healthy hair and a balanced biome will be at your fingertips in no time.

    Finally, something that works!

    I love the Head Doctor Conditioning Treatment. Not only does it soothe my scalp, which suffers from eczema, but it also leave my hair soft and smooth.

    Game changer

    I had quite high expectations of this product due to all the hype and reviews and it delivers. I am only using the conditioner at the moment and think I would get even better results with the shampoo and serum, as I am still experiencing some dryness and eczema along my hairline. I also have pretty dead hair and this does a decent job at making it more hydrated, but it doesn’t replace use of needing hair oils and masks. Honestly most dandruff products in the past make my hair worse, but this is just great
