# Training Junior Stylists on Keratin: Avoiding Costly Re-Dos

**By 365 SUN Editorial** · 2026-11-09

Every keratin re-do costs your salon product, an unpaid hour in the chair and a little client trust. Most re-dos trace back to a few technique gaps. Here is how to train junior stylists to get it right the first time.

## 1\. Consultation first

Teach assistants to check hair history: bleach, box dye and previous treatments change processing. A strand test on compromised hair prevents most surprises.

## 2\. Clarify properly

Residue blocks absorption. Two thorough washes with the clarifying step are non-negotiable.

## 3\. Thin sections, even application

Too much product leaves hair heavy and greasy; too little leaves frizz. Practice with thin sections and combing product through from root to tip, leaving a small gap at the scalp.

## 4\. Dry 100% before ironing

Ironing damp hair causes steam, damage and patchy results. Make "fully dry" a checklist item.

## 5\. Iron temperature and passes

Set the iron by hair type and limit passes. Overworking is a top reason for breakage complaints.

## 6\. Shadow, then supervise

Use a three-stage plan: the junior watches, assists, then performs while a senior checks each step. Start with practice heads or model clients.

## Consistent system, consistent results

Using one reliable system makes training easier. The [Cadiveu Brasil Cacau 3-Step Kit](https://www.brkeratin.biz/products/brasil-cacau-reconstruction-kit-big-3-products) and the [Brasil Cacau 300 ml Set](https://www.brkeratin.biz/products/brasil-cacau-thermal-reconstruction-300-ml-10-1-fl-oz-set) give your team a clear, repeatable protocol and fewer costly re-dos.
