Keune Ammonia-Free Color: Benefits for Sensitive Scalps

If your scalp tingles, burns, or itches during a color service, ammonia is often the reason. Ammonia opens the cuticle aggressively, which is why permanent color lifts so well, but it also creates the sharp smell and scalp reaction many clients want to avoid. Keune So Pure is a professional ammonia-free color line that delivers salon-quality deposit and soft lift without the irritation. Here is why it is a smart choice for sensitive scalps and when to reach for it.

What Ammonia Does in Hair Color

Ammonia is an alkalizing agent that raises the pH of color, which opens the hair cuticle so pigment can deposit inside the strand. It also activates the lifting process when paired with developer. The drawback is that ammonia is volatile, it produces a strong odor, and it can irritate sensitive scalps, eyes, and airways. Some clients experience itching, redness, and prolonged tingling.

How Keune So Pure Works Without Ammonia

So Pure uses a monoethanolamine (MEA) base along with botanical extracts and essential oils to open the cuticle more gently. It still deposits color effectively and offers up to 2 levels of lift when paired with the right developer, but without the sharp scent or harsh scalp reaction of ammonia-based formulas. It also conditions the hair during processing thanks to its botanical ingredient profile.

Signature So Pure Ingredients

• Lavender oil: calming for the scalp
• Sage and rosemary extracts: support scalp balance
• Jojoba oil: adds softness and shine
• No ammonia or silicones in the formula

Who Benefits Most from Ammonia-Free Color

Not every client needs ammonia-free color, but for the following groups it makes a real difference in comfort and results.

• Sensitive scalps: clients who react to permanent color with itching, burning, or redness
• Frequent colorers: anyone coloring every 4 weeks benefits from a gentler formula
• Chemically treated hair: relaxed, keratin-treated, or previously lightened hair
• Pregnant clients (with physician approval): many prefer the lower-odor option
• Older clients: scalp skin thins with age and becomes more reactive

So Pure Mixing and Application

So Pure uses a 1:2 mixing ratio with So Pure Cream Developer. That means for every 60 ml tube of color, mix with 120 ml of developer. This thinner consistency applies smoothly and saturates evenly.

• Developer choice: 6 Vol for tone-on-tone, 10 Vol for soft lift, 20 Vol for up to 2 levels of lift
• Processing time: 20 minutes for deposit, up to 35 minutes for full lift
• Application: same technique as permanent color, work in clean sections for even saturation

What to Expect vs. Permanent Color

Because So Pure is gentler, the results are softer than a heavy permanent color. You will see fewer levels of lift and somewhat faster fade compared to a strong permanent formula. For clients who prioritize comfort and hair integrity, that trade is worth it.

• Gray coverage: blends up to about 70%, best on less than 50% gray
• Lift: up to 2 levels on natural hair
• Longevity: approximately 4 to 5 weeks before a refresh
• Hair condition: noticeably softer and shinier after service

Tips for Maximizing Longevity

• Rinse with cool water to close the cuticle
• Use a sulfate-free shampoo like Keune Care Color Brillianz
• Wait 48 hours before the first wash after service
• Refresh between retouches with a So Pure gloss

When to Choose Permanent Over Ammonia-Free

If the client has more than 50% gray, wants a dramatic 3-level lift, or needs maximum longevity, permanent Keune Tinta is still the better tool. Many stylists use both: So Pure on sensitive clients or refresh services, and Tinta for full gray coverage or significant color changes. A hybrid service with Tinta at the root and So Pure through the mid-lengths and ends is another strong option for sensitive-scalp clients who also need gray coverage.

Scalp Prep for Sensitive Clients

Even with an ammonia-free formula, sensitive scalps benefit from a few prep steps. Start with a clean, dry scalp and avoid any scratching or exfoliation in the 24 hours before service. Apply a thin barrier cream along the hairline to prevent staining without blocking pigment absorption. If the client has a history of contact dermatitis, run a 48-hour patch test behind the ear before the full service to confirm tolerance to the formula.
