Good gray coverage on main portion of hair
Same resulting color as the creme formula
Excellent conditioner, generous amounts
Tends to run
Does not color maverick strays (particularly grays around the hairline)
Difficult to rinse out
Causes very stubborn tangles, increasing risk of mechanical damage
I've been coloring my hair at home to cover gray for about ten years. When Garnier came out with the Color Foam, my local store decided to replace the cream formula with the new foam formula. Unwilling to blindly switch to another brand or wait to do my research, I grabbed the Color Foam box in my color - 3-Darkest Brown.
One of the selling points of this new formula was the "no stress, no mess application". While the foam mixed up easily and didn't splatter when colorant levels in the bottle were low (like the creme), it dripped when I wasn't careful to check all areas of my glove. I think the formula condensed on the glove when the bubbles burst and whatever was left behind returned to its liquid state. It was very difficult to apply the product with any precision, and stains seem to be unavoidable. They're larger and more frequent than with the creme formula.
I have had great results just coloring my regrowth every 4-5 weeks, so I applied the foam to regrowth only, contained the remaining dry hair with a ponytail holder, and went to sit (carefully) in the living room and watch some TV while my color processed. I had to get up several times to catch trickles of color trying to run off my scalp. In later experiences, I chose to smoosh the hair over the area where the trickle was starting and that stopped most of them.
Gray Coverage and Resultant Color
Around my hairline, I have some stubborn grays that stand away from the rest of the hair and won't lie down. I found these extremely difficult to color. Although I was careful to deposit foam on them, it didn't stay. After washing the color out, I found that the grays were just slightly tinted instead of fully covered like the grays in the rest of my hair. Grays in the main portion of my hair stay well covered for 4-6 weeks. The resulting color looks the same as the creme formula.
Rinsing Out the Color
Washing the color out was very difficult. We have low water pressure, which didn't help. The worst part was the texture. The foam makes my hair very grabby and tangly. It was impossible to get my fingers through the hair, much less a comb. It was like combing through velcro. The first time, it took so long for the water to run clear that I eventually settled for "mostly clear" and put a towel over my pillow to catch the transfer. My scalp was itchy and my hair bled dye for days.
After several tries with this product, I find that the best approach is to start with a very wide tooth comb and work the tangles out from the ends in order to rinse the color out. However, even using this method it's a long time before the water runs clear and I still have tangles. Furthermore, I'm concerned that all this detangling with wet hair increases the risk for mechanical damage.
The conditioner leaves my hair glossy and soft, and comes in a large tube. I have very thick, hip-length hair, but one tube lasts four weeks with an initial all-over application and twice-weekly application to the length and ends after that.
I've given this formula a good try and I'm confident that the inconvenient application and less-than-stellar results are a consequence of a less-than-stellar formula, not user error. So although the color result is lovely, I will choose the creme formula or another brand for the future.
