TL;DR:
- Hair masks deliver deep moisture and softness. Hair treatments rebuild structure and repair damage. They do different things.
- Dry or frizzy hair: start with a mask used weekly
- Damaged, bleached, relaxed or breaking hair: add a treatment (Olaplex No.3) to your routine
- Best results: use both — treatment for repair, mask for ongoing moisture maintenance
- All products below are stocked and recommended by our Cape Town salon team
"Do I need a hair mask or a hair treatment?" — it's one of the most common questions our stylists hear, and it's a genuinely good question because the answer changes what you buy. The two products do different things, and using only one when you need both is why many clients feel like their routine isn't working. Here's how to tell them apart.

The Key Difference
| Feature | Hair Mask | Hair Treatment |
|---|---|---|
| Purpose | Deep hydration and conditioning | Repair, strengthen and rebuild |
| How often | Weekly, in place of conditioner | Weekly or as directed (some daily) |
| Contact time | 5 to 20 minutes | 10 to 45 minutes, or leave-in |
| Best for | Dry, dull, frizzy hair | Damaged, bleached, relaxed or breaking hair |
| What it delivers | Softer, smoother hair | Stronger, healthier hair long-term |
"The simplest way I explain it to clients is this: a mask feeds the hair. A treatment rebuilds it," says Judy, head trainer. "If your hair is dry but structurally sound, a mask is what you need. If it's breaking, weak, or has been through bleach or relaxing services, you need a treatment. Many clients need both."
The Best Hair Masks We Recommend
1. Moroccanoil Intense Hydrating Mask — Best Overall
Rich argan oil mask that restores moisture in 5 to 10 minutes. Works on fine, medium, and thick dry hair. One of the most consistent performers in our range for clients who need moisture without heaviness.
"Moroccanoil Intense Hydrating Mask is what I reach for first when someone has dry, dull hair and wants immediate softness," says Jackie at Gardens Centre. "The argan oil content is high, the texture is rich without being heavy, and clients notice the difference from the first use."

2. Kérastase Nutritive Masquintense — Best for Very Dry Hair
Ultra-nourishing mask for thick, dry or coarse hair. The Legere version is formulated for fine dry hair. Both sit in the hair for five to ten minutes and deliver intensive moisture at a level standard conditioner can't reach.
The Best Hair Treatments We Recommend
1. Olaplex No.3 Hair Perfector — Best Bond Repair Treatment
The most widely used at-home bond repair treatment. Applied to dry or damp hair before shampooing, left on for a minimum of 10 minutes (longer for more damaged hair). Reconnects broken disulfide bonds caused by bleach, colour, and heat. Our top-selling treatment year-round.
"Olaplex No.3 is the treatment I recommend before anything else for clients whose hair is breaking or has been chemically processed," says Royston at Cavendish. "Nothing else at-home addresses bond damage at this level. It's genuinely different from a mask — it's structural repair, not surface conditioning."
2. L'Oréal Professionnel Absolut Repair Molecular Mask — Best for Strengthening
Intensive molecular repair for weak, brittle and chemically treated hair. Applied after shampooing, before conditioner, as a leave-in treatment. Visibly stronger hair after consistent use — particularly effective alongside the Absolut Repair shampoo and conditioner for a complete repair routine.

Which One Should You Use?
Dry or frizzy hair only? — Weekly mask. Start with Moroccanoil Intense Hydrating or Kérastase Masquintense.
Damaged, bleached, relaxed or breaking hair? — Weekly treatment (Olaplex No.3 is our most recommended). Add a moisture mask alongside it.
Both concerns at once? — Use both. Olaplex No.3 pre-shampoo once a week for repair. A moisture mask in place of conditioner on the same or alternate weeks. They address different problems and don't conflict.
How to Use Each Correctly
Hair mask: Apply after shampooing on damp hair. Focus on mid-lengths to ends. Leave 5 to 10 minutes. Rinse well. Used in place of conditioner once a week.
Olaplex No.3: Apply to dry or damp hair before shampooing. Leave a minimum of 10 minutes — longer for more damaged hair. Then shampoo and condition as normal.
L'Oréal Absolut Repair Molecular Mask: Applied to clean, towel-dried hair after shampooing. Leave-in — not rinsed. Then condition and style as normal.
Frequently Asked Questions
Can I use a hair mask and a treatment together?
Yes. Use Olaplex No.3 before shampooing, then after shampooing follow with a moisture mask in place of conditioner. The treatment addresses structure; the mask addresses moisture. They complement each other.
How often should I do a hair mask?
Once a week for most hair types. Very dry or coarse hair can mask twice a week. Fine hair should keep it to once to avoid flatness.
Is Olaplex a hair mask or a treatment?
It's a bond-building treatment, not a traditional mask. It works at the structural level inside the hair shaft, not just on the surface. The contact time and mechanism are both different from a conditioning mask.
My hair is both dry and damaged — what should I do?
Both products, used consistently. Olaplex No.3 weekly for the repair side. A moisture mask weekly for the hydration side. This is the most common routine we build for clients with bleached or relaxed hair that's also feeling dry.
