Clairol Professional vs. Superstar Developer: Which One to Buy, and How Many Bottles You Need

Hair So Good carries two developer lines side by side: Clairol Professional Cream Developer (16oz, in 20/30/40 volume) and Superstar Cream Peroxide Developer (4oz, in 20/30/40/50 volume). For volume strength itself, see our Developer Volume Guide. This page covers the question that guide doesn't: which brand and bottle size to actually buy, and how many you need for the job.

Clairol Professional vs. Superstar -- what's the real difference?

	Clairol Professional	Superstar
Bottle size	16oz	4oz
Volumes offered	20, 30, 40	20, 30, 40, 50
Best for	Full-head color, salon-scale or repeat use	Root touch-ups, single small applications, or trying a new volume before committing to a large bottle

The core chemistry (peroxide-based cream developer) is the same category of product in both -- the real difference driving which to buy is bottle size relative to the job, not a meaningful formula gap between the two brands.

How many bottles do you need for a full head of color?

Professional colorists mix developer with color at a standard 1:1 or 1:2 ratio, a convention set by color-line manufacturer instructions rather than this guide's own estimate -- check the specific color product's own directions for which ratio it calls for. At that standard ratio, a full head of color on shoulder-length hair conventionally draws on 4-8oz of mixed product total (color plus developer combined), with longer or thicker hair needing more.

• One 16oz Clairol Professional bottle holds enough developer alone for several full-head applications at a standard mixing ratio, making it the better buy for anyone coloring regularly or doing multiple clients.
• One 4oz Superstar bottle is sized for a single full-head application on shoulder-length hair at a standard ratio, or several smaller touch-ups -- a better fit for occasional, single-use needs.

Buying the small 4oz size for a full-head job on longer or thicker hair risks running short mid-application, since developer needs to be mixed and used promptly once combined with color and can't be topped up cleanly partway through.

Which one should you buy?

Buy Clairol Professional (16oz) if you color your own or others' hair more than occasionally, or if the head being colored is longer than shoulder-length. Buy Superstar (4oz) if this is a single touch-up, a root refresh, or you want to test a specific volume strength before committing to a larger bottle.
