Here are a few products that I use in my hair everyday. I use these products to maintain moisture so my hair will not experience dryness and breakage. Some products are inexpensive, but they are all under $10.
Organic Root Stimulator Hair Mayonnaise $9.99. I use this at least once a week to deep condition. I leave in my hair for thirty minutes or an hour. This product is good for relaxed and natural hair. It is especially great for use after dying hair to re-add moisture to your hair.
This product does the same at the Organic Root Stimulator, but it a cheaper alternative to paying $9.99. I purchased this for $3.50 at my beauty supply store.
Doo Gro oil is great for using if you are going to put hairgel in your hair. Gel can dry your hair and leave it feeling crunchy. I use this oil in my hair while it is still damp and then apply eco-styler gel to my hair.
