Build-up Causes & Symptoms

Build-up is caused by water used to cleanse and condition hair — hard water and soft water alike…

Hard water contains calcium, magnesium, iron and copper at different levels. Softened water contains potassium and salts— all minerals contributing to further build up!

For those with color treated/highlighted hair mineral build-up shows up in brassy tones and hair color fades fast.

For those who have never colored/highlighted their hair mineral build up shows up as a dull lack-luster tone of the color their hair once was.

Other Symptoms: Dry, frizzy, hard to the touch strands, limp curls, yellowing grays and/or moisture resistant curls.

Build-up can also be caused by:

  • Hair Gel, Curl Foams, Hair Sprays, Dry Shampoos

  • Chlorine

  • Salt Water

  • Silicones

  • Emollients

  • Heavy Oils (ex. shea butter, coconut oil and olive oil)

  • Improper cleansing and over conditioning

Wavy, curly and coil-y curl types are most susceptible to build-up due to the shape/structure of the hair strand.
