Each Caboki entry is quoted or computed from a caboki.com page fetched on October 2, 2026. Where caboki.com does not state a fact, the cell says so rather than guessing. Prices are US dollars before tax and shipping. Websites change, so the date is part of each fact.

Is most. or Caboki keratin?

Neither is keratin. most. hair fibers are made of cotton cellulose and contain no keratin and no wool protein. Caboki's FAQ says it is made of "Plant fibers extracted from Gossypium herbaceum, a variety of cotton (also called Levant cotton)", and its About page says Caboki is "free from animal-derived keratin". Both are plant fibers.

The lists differ after the fiber. most. publishes seven entries: cotton cellulose, cellulose gum, sodium chloride and four mineral pigments by CI number (CI 77491, CI 77492, CI 77499, CI 77891). Caboki prints two components, "Gossypium Herbaceum (Levant cotton) fiber, mineral colorants (Iron oxide)", and its ingredients page says "Caboki is made of two ingredients." Caboki does not print CI numbers.

On animal origin, most. is vegan and not tested on animals. Caboki's ingredients page states: "Our products do not contain any ingredients derived from animals." The full most. label transcription is on the most. ingredients page.

Which has more shades, most. or Caboki?

Caboki has more shades. Its product page lists 14 colors, including two grays, a silver/white, two salt and pepper shades and two auburns. most. makes four: Black, Dark Brown, Light Brown and Blonde. most. makes no grey, white, red or auburn shade, so for those hair colors Caboki lists shades that most. does not make.

The two brands handle a near miss differently. Caboki's FAQ says: "If your hair doesn't match any single shade exactly, we recommend ordering the two closest colors and applying both to blend a custom match." most. offers a free shade swap, forever, with no return needed: email the shade you have and the shade you want. A swap fixes a mismatch inside four shades. It does not create a shade most. does not make.

Both brands give the same matching rule. Caboki's FAQ says to look at "the color of your hair at the root in the thinning area", and the most. shade guide matches to the root, in daylight.

Which is cheaper per gram, most. or Caboki?

Caboki is cheaper per gram at the one-bottle price. Caboki 30 g costs $34.95, and $34.95 divided by 30 g is $1.17 per gram. most. costs $39.95 for 25 g, and $39.95 divided by 25 g is $1.60 per gram. The Caboki 16 g bottle is $19.95, and $19.95 divided by 16 g is $1.25 per gram.

On subscription, Caboki 30 g is $29.71, and $29.71 divided by 30 g is $0.99 per gram. most. is $29.95 for 25 g, and $29.95 divided by 25 g is $1.20 per gram. most. also sells multi-bottle packs one time: four bottles (100 g) for $71.80 is $0.72 per gram, three bottles (75 g) for $59.85 is $0.80 per gram, and two bottles (50 g) for $49.90 is $1.00 per gram. The Caboki product page fetched on October 2, 2026 shows no multi-bottle price.

These figures leave out shipping, tax and Caboki's reward points, which its subscription page describes as "10% of your money back as credit on each purchase." Grams used per day depend on the size of the area covered, so price per gram is not the same as price per application.

What does each guarantee actually cover?

Both brands offer 30 days. most. refunds the first order within 30 days of delivery, sends a prepaid return label, and refunds used or empty bottles in full. Caboki's refund policy says to return the products within 30 days of receipt for "the entire purchase price, (minus the shipping fee, if applicable), no questions asked."

Caboki's policy adds: "You don't need any return authorization number," and refunds are processed "within 3 business days" of the return arriving at its Cranbury, New Jersey address.
