Hair Dye Basics and Demi-Permanent Dye Application

See how I apply demi-permanent color to my hair in this easy-to-follow, informational tutorial.

In addition to watching, please read my full explanation of how hair dye works, factors that affect results and questions you can use during a consultation with a stylist at

NOTE: It is always my recommendation that you consult a professional colorist or stylist in your area before making any decisions about chemically altering the color of your hair. Even if you intend to do it yourself, it is good to know if what you are considering is actually feasible. Hair dye is not a “one size fit all” process. No two people will get the exact same result because everyone’s hair is different. Using what you see others use or guessing can be a costly, damaging, irreversible mistake. This is not meant to discourage you from ever dying your hair, but to arm you with information you need to make a wise, conscious decision!

    Mo, I used the Ion Demi on my 25% gray. I color every 4 weeks, due to quick hair growth/roots show quickly. I was using the ion ammonia free line but wanted to switch to demi. My greys came out lighter/red than the rest of my hair. I have dark brown hair. I left it on for 25 minutes, used the pre color treatment spray and the after color sealer. How long should I wait until I can put another demi application on my hot roots? My hair holds onto moisture,. Though I would mention that in case it helps. I have thick wavy hispanic hair.

    I just started my hair journey and ran across your site.  I see that you attended Cosmetology School and am soo appreciative for the content of your videos.  When trying new ideas, styles or just learning about hair in its "natural state" you have become my "go to" vlogger.  Thank you so much for the time and extensive commentary you narrate on each video.  Your videos are always quick, professional and straight to the point.  I visited your site and hoped that you were located in California because you were going to become my new BFF! lol However I see that you live elsewhere.  Should you ever decide to move here please be sure to let us know and I'll be the first in the chair. Thanks for your knowledge and professionalism. For those who really want to "understand" our hair and how to best care for it, your videos are Priceless! Much success to you Mo!
