PERMANENTHenna is permanent. It's a natural plant. It's not a chemical create in a lab nor is it ink. The henna plant only makes one color: Red.
CUMULATIVEThe effect of henna on your hair color is cumulative--meaning that each time you do a treatment, your color will get deeper and richer. It takes a few days for your henna to fully oxidize and produce the finished effect.
HEATUsing a warm henna paste + sitting under the dryer after applying your henna will give your hair a deeper richer color.

DOES NOT LIGHTEN HAIRHenna can not lighten your hair tone. Henna does not open the cuticle and lift or lighten your hair's natural hair pigment. Henna coats your hair like a varnish, which means your individual shade sits underneath the henna, creating a color that's unique to you. Essentially, henna stains your hair the same way that a beet will stain whatever it touches. The result is a mix of the red from the beet and whatever color the object was before the beet touched it.
INDIGOIndigo is not henna. It's another plant that can be used to dye/stain your hair. When mixed with henna it creates brown hues.
CASSIACassia obovata is not henna. It's another plant that can be used to dye/stain your hair. Cassia has a yellow tint that typically doesn't show up on dark hair. Thus it's been called "neutral henna" because it has many of the same benefits of henna without the color.

|Curl Loosening Theory From JC @ NaturalHairHaven|
CURL LOOSENINGHenna can loosen your curl pattern. According to my favorite Curly Scientist, with each henna application your hair absorbs the henna, but it also absorbs water. The henna + water combo weighs the strands down thus elongating the curl. If you strip all the science-y stuff away, to me, it sounds like henna can "over-moisturize" your hair depending on your hair's texture, porosity, and the frequency of henna use. I have noticed that my curls are more elongated following my henna applications. However, my curl returns to normal a few days later. My curl definition has also changed. When my hair is wet, it's a bit more frizzy, however when it dries (for example in a wash and go) the definition is actually greater and it lasts.
DRYINGHenna can be drying. The drying affects of henna can be combated by applying an oil to your hair before application, adding moisturizing ingredients to your recipe or deep conditioning your hair after application. I like to deep condition for at least an hour under my hooded dryer or over night after henna treatments.
APPLICATIONApplying henna to damp hair makes the application process easier. I like to co-wash my hair before applying my henna paste.
STRAND AND PATCH TESTAlways perform a patch test on your skin then a strand test on your hair of your henna paste before using. This video by Chemese about her severe allergic reaction to what she thought was henna should be enough to convince you. Because I love my hair and I can be stupid paranoid, I've only used Lush's Caca Rouge. Lush's henna treatments are premixed and reputable.
For right now, the pros of henna outweigh the negatives. I'm extremely happy with the health of my hair and the hair is EVERYTHING!
