Product buildup can be a huge problem for all hair types. But, it isn't always easy to spot. In fact, many people with product buildup assume they just have low porosity hair.

Porosity is the ability of hair to absorb moisture. It's measured by a strand test and can be high, medium or low.

Low porosity hair vs high porosity hair

If you have low porosity hair, it's likely that your strands are resistant to moisture and can often be dry. Ironically, the tight cuticle often creates a high-shine effect in low porosity hair. High porosity hair is easily penetrated by moisture, but can also lose moisture more quickly. This is because the size of the hair shaft determines how easily it can absorb water and allow it to pass through the cuticle layer. If there are gaps in this protective layer, more water will be able to penetrate into the cortex where it causes swelling that makes individual strands swell up or expand. The result? Frizz!

Product buildup can often be disguised as low porosity hair.

All products have the ability to cause buildup if not cleansed away properly. However, more long-term product buildup is often caused by silicones. Silicones, commonly found in conditioners, create a barrier around the hair shaft to produce a temporary effect of shine and manageability. However, silicones are not easily shampooed away like other care product ingredients.

Find a gentle clarifying shampoo.

Clarifying cleansers, like our RESET, can help remove product buildup. To combat buildup caused by silicones, discontinue use of silicone products and continue clarifying with a cleanser gentle enough for weekly use. You will see improvement over the course of a month or two.

It's important to understand the difference between porosity and product buildup. Knowing what's actually going on with your hair will allow you to care for it better.
