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.


DEFENSCALP™ is an anti-dandruff agent that works to rebalance your scalp microbiome without irritating you or your scalp. It’s speciality, is hydrating dry skin and strengthening the skin barrier, all while helping to soothe scalp concerns.


Reduces hair porosity while strengthening it from within resulting in healthier and shinier hair. Increases your hair’s ability to receive and retain moisture. Helps reduce breakage, eliminates frizz and tangles and makes your hair appear fuller. Leaves a protective film that protects against daily stresses. It holds anti-inflammatory properties, which help to soothe the scalp.

    Blown away!

    I unboxed my Straand products and immediately applied The crown fix serum to my 'trouble spot' on my hairline behind my ear. I took a before photo with the intent of taking an after photo in a few weeks time, having used the product enough to hopefully see a difference. I checked it again after a few hours and immediately snapped the after photo. I am completely blown away at the improvement after only one application of this product. The redness has been reduced dramatically! I cannot wait to see my results with continued use!

    The Missing Ingredient

    After using the shampoo and conditioner for a few months with little reprieve from the flake I thought I would try this serum. Game changed! My scalp is tonnes better and the flake has abated... Hooray!

    Love it!

    I absolutely love this product. I have a dry itchy scalp and this is amazing to soothe those areas. It doesn't leave your hair greasy or anything and it works instantly.

    My only comment is I would love the dropper to be smaller, so a smaller amount of product is placed at once and can be more targeted but that's personal preference!

    100% recommend this!
