Keratin Treatment: How Long Does It Last depends on your hair type and how well you take care of it. Usually, it lasts between 2 to 6 months. If you use sulfate-free shampoos, avoid too much washing, and protect your hair from heat and saltwater, the results stay longer. While the treatment makes your hair smooth and shiny, some people may face side effects like dryness, hair fall, or irritation due to strong chemicals. Always ask a hair expert before getting it done.
- Fine or thin hair: This type may last around 2–3 months because natural oils and frequent washing can break down the treatment more quickly.
- Thick or curly hair: Can last 4–6 months since the hair holds the treatment longer and sheds natural oils more slowly.
- Aftercare & maintenance: Proper care can extend results, while excessive heat styling, chlorine, or saltwater exposure may shorten its lifespan.
Best Tips to Make Keratin Treatment Last Longer
- Wait 48–72 hours before washing hair to let the treatment fully set.
- Use sulfate-free shampoo to avoid stripping the it
- Wash hair less often (2–3 times a week) to preserve the treatment.
- Avoid saltwater & chlorine, or wear a swim cap to protect hair.
- Use heat protectant sprays before styling to prevent damage.
- Apply it to friendly conditioners to maintain smoothness.
Possible Side Effects of Keratin Treatment
- Formaldehyde risk: Some treatments have strong chemicals that can make your scalp itchy or cause breathing problems. Pick ones that don’t have formaldehyde.
- Dry or weak hair: Too much heat can make your hair dry and prone to breaking easily.
- Hair fall: This doesn’t happen often, but strong chemicals can sometimes cause hair to fall out.
- Flat look: Your hair might look less full, especially if it’s already fine or thin.
Factors Affecting Keratin Treatment Longevity
1. Hair Porosity & Texture
It depends on your hair type, like how thick or thin your strands are and how well they hold moisture (that’s porosity). At Anam’s Vanity, we see most curly hair clients enjoy 3-4 months of smoother, frizz-free curls before needing a touch-up.
- Low porosity hair (absorbs moisture slowly) may not hold the treatment as well, making it fade faster.
- High porosity hair (absorbs moisture quickly) absorbs the treatment better but may lose it faster due to moisture exposure.
- Thick or coarse hair holds keratin longer, while fine or thin hair may see quicker fading.
2. Washing Frequency & Water Hardness
How often you wash your hair and the kind of water you use can affect how long the keratin treatment lasts.
Less volume: Hair may look flat, especially if it is naturally thin or fine.
- Washing too often (especially in the first week) strips the treatment faster.
- Hard water (high in minerals) can cause buildup, making the treatment wear off quicker.
- Use lukewarm water instead of hot water to preserve the treatment longer.
3. Exposure to Chlorine & Saltwater
Chlorine (in pools) and saltwater (from the ocean) can break down its treatments.
- Chlorine dries out hair and weakens the treatment.
- Saltwater strips moisture, making hair rough and causing the treatment to fade.
- Always rinse hair with clean water before swimming and use a protective leave-in conditioner.
4. Use of Sulfate Shampoos
Sulfates are harsh cleansers that remove natural oils from hair.
- Sulfate-free shampoos are gentler and help the treatment last longer.
- Avoid shampoos with sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES).
- Use a moisturizing, color-safe shampoo to maintain smoothness
Fading Time: What to Expect & How to Prolong Results
Gradual vs. Sudden Fade-Out
The treatments don’t disappear overnight—they fade gradually over time. However, how quickly they fade depends on:
- Gradual Fade:
- Hair slowly returns to its natural texture.
- Smoothness and shine reduce over the weeks.
- Common with professional treatments (lasts 2–5 months).
- Sudden Fade:
- Happens if harsh products (sulfates, chlorine) are used.
- Hair may frizz or lose straightness quickly.
- Occurs with at-home treatments (may last only 4–6 weeks).
Signs Your Treatment Is Wearing Off
Look for these clues:
✔ Increased frizz or puffiness
✔ Hair doesn’t stay straight after washing
✔ Loss of shine and smoothness
✔ More tangles and dryness
