Building a Shampoo Rotation
No single shampoo does everything, which is why a rotation beats brand loyalty. The practical setup is two to three shampoos, a gentle daily or regular wash like the Davines OI, a clarifying shampoo for monthly resets, and optionally a targeted formula for specific needs. A sample week might run gentle washes on most days with one clarifying wash every third week, adjusted for how much product you use. Heavy stylers and dry shampoo push the clarifying need up, while minimal routines can stretch it out. The rotation prevents both buildup from using one rich shampoo endlessly and dryness from over-clarifying. Write the rotation down for the first month until it becomes habit.
The Concentration Question: Cost Per Wash
Salon shampoos claim to last longer, and concentration is why the claim often holds. A concentrated formula needs a smaller amount per wash, so a 9.47 oz Davines OI bottle can outlast a 13 oz drugstore bottle used generously. The fair comparison is cost per wash, divide the bottle price by the estimated number of washes, not by ounces. Diluting concentrated shampoo slightly in the palm also improves distribution on long hair. The refill format exists precisely for this math, since refills cut the per-ounce cost significantly for committed users. Judge value by months per bottle at your actual usage, which is the only number that affects your wallet.
When the Shampoo Stops Working
A shampoo that worked for months and suddenly disappoints has a diagnosable cause. Product buildup is the most common, where layers of conditioner and styler shield the hair from cleansing, and one clarifying wash usually restores performance. Hard water mineral film is the second suspect, especially if dullness crept in gradually. Expired product is the third, since opened shampoo degrades over twelve to eighteen months. Hormonal changes and seasonal shifts round out the list. Work through these in order before abandoning a trusted shampoo, since most cases resolve at step one or two. The Davines OI routine guide details the full line, and the OI oil guide covers the finishing step.
