Bleached hair is beautiful, bold, and expressive—but it also requires careful maintenance. One of the most common questions I hear as a hairstylist is: “How often should I wash bleached hair?” The answer isn’t straightforward because it depends on your hair’s unique needs.
This essay will break down the science of bleached hair, factors that influence washing frequency, and practical tips to keep your hair healthy. Let’s dive in!
Understanding Bleached Hair Structure
To determine how often to wash bleached hair, you must first understand how bleaching affects your hair.
What Happens During Bleaching?
Bleaching is a chemical process that removes your hair’s natural pigment (melanin). To do this, the bleach lifts the hair’s cuticle—the outer protective layer—and penetrates the cortex (inner layer).
This process weakens the hair by:
- Stripping natural oils: Your scalp produces oils (sebum) to moisturize hair. Bleaching disrupts this balance.
- Damaging proteins: Hair is made of keratin, a protein. Bleaching breaks down keratin, making hair brittle.
- Increasing porosity: Bleached hair becomes more porous, meaning it absorbs water (and products) quickly but loses moisture fast.
Why Does This Matter?
High porosity + lack of natural oils = dry, frizzy, and fragile hair. Overwashing can worsen these issues by stripping away moisture, leading to breakage or split ends. However, underwashing can cause product buildup or scalp irritation. Finding the right balance is key.
Factors That Influence Washing Frequency
There’s no universal rule for washing bleached hair. Consider these factors:
Scalp Type
- Oily Scalp: If your scalp produces excess oil, you might feel the need to wash frequently. However, bleached ends are dry. Solution: Use shampoo only on the roots and condition the ends. Try dry shampoo between washes.
- Dry Scalp: If your scalp is flaky or itchy, overwashing can worsen dryness. Opt for moisturizing shampoos and wash less often.
Hair Texture and Type
- Straight Hair: Oil travels faster down straight strands, making roots greasy sooner. Wash every 2–3 days.
- Curly/Wavy Hair: Curls are naturally drier and prone to frizz. Washing once a week may suffice.
- Thick vs. Thin Hair: Thin hair shows oil more quickly. Thick hair can go longer between washes.
Porosity Level
High-porosity hair (common in bleached hair) loses moisture rapidly. If your hair feels dry shortly after washing, reduce washing frequency and focus on hydration.
Lifestyle and Environment
- Exercise/Sweat: Sweat can irritate the scalp. Rinse hair with water after workouts and use conditioner instead of shampoo.
- Pollution/Humidity: Pollution particles stick to porous hair. Clarify occasionally (but gently!).
- Styling Products: Heavy gels or sprays require more frequent washing. Use lightweight products.
Recommended Washing Frequency
Based on the factors above, here’s a general guide:
- Straight, Fine Hair: Every 2–3 days.
- Curly/Thick Hair: Every 5–7 days.
- Oily Scalp: 3–4 times a week (focus shampoo on roots).
- Dry Scalp: 1–2 times a week with a hydrating shampoo.
Adjust as Needed: If your hair feels straw-like, wash less. If your scalp itches, wash more.
Proper Washing Techniques
How you wash matters as much as how often.
Pre-Wash Care
- Brush hair gently to detangle.
- Apply coconut oil or a pre-shampoo mask to protect ends.
Shampooing
- Use lukewarm water (hot water dries hair).
- Choose a sulfate-free shampoo to avoid stripping moisture.
- Massage scalp gently—don’t scrub lengths.
Conditioning
- Apply a moisturizing conditioner from mid-lengths to ends. Leave for 3–5 minutes.
- Rinse with cool water to seal the cuticle.
Post-Wash Care
- Pat hair dry with a microfiber towel—no rubbing!
- Apply leave-in conditioner or hair serum.
Product Recommendations
- Shampoo: Olaplex No. 4 Bond Maintenance Shampoo (repairs bonds).
- Conditioner: Shea Moisture Manuka Honey Mask (intense hydration).
- Dry Shampoo: Batiste Original (absorbs oil without residue).
- Leave-In: K18 Leave-In Molecular Repair Mask (strengthens keratin).
Aftercare and Maintenance
- Deep Condition Weekly: Use a protein-rich mask like Olaplex No. 8.
- Limit Heat Styling: Always apply heat protectant.
- Protect from UV/Chlorine: Wear a hat or use a UV-filter spray.
- Trim Regularly: Every 8–12 weeks to prevent split ends.
Common Mistakes to Avoid
- Overwashing: Leads to dryness and breakage.
- Skipping Conditioner: Bleached hair needs constant moisture.
- Using Harsh Towels: Cotton towels cause friction—use microfiber.
- Ignoring Scalp Health: A healthy scalp = healthy hair.
Conclusion
Bleached hair requires a tailored approach. Start with washing 2–3 times a week, adjust based on your scalp and hair type, and prioritize hydration. Remember: less is often more! When in doubt, consult your stylist for personalized advice. With the right care, your bleached hair can stay vibrant, soft, and strong.
