Hair feeling heavy, coated, or refusing to absorb products? Silicone buildup is likely the culprit. When non-water-soluble silicones layer on your hair over time, they create a barrier that prevents moisture from penetrating, leaving hair progressively duller and more lifeless despite regular conditioning.
Removing silicone requires more than regular shampooing. The same water-resistant properties that make silicones effective for smoothing and shine also make them difficult to wash away. This guide covers 10 proven methods to remove silicone buildup, essential aftercare to prevent damage, and strategies to maintain silicone-free hair in Australian conditions.
To remove silicone from hair, use clarifying shampoo with sulfates or strong surfactants to break down buildup (2-4 washes needed). Natural options include baking soda paste or apple cider vinegar rinse. Critical: follow with deep conditioning as removal reveals dehydrated hair texture. Prevent buildup by choosing water-soluble silicones or silicone-free products.
What Causes Silicone to Build Up on Hair?
Silicone buildup happens when dimethicone, cyclomethicone, or amodimethicone accumulate faster than they're removed. These synthetic polymers coat hair strands to create shine and smoothness, but they're designed to resist water. Regular shampoos can't break down these layers effectively.
Each application adds another thin coating. Initially, this creates the glossy effect people seek. After weeks or months of use, multiple layers trap natural oils, block moisture absorption, and make hair feel increasingly heavy. Products stop penetrating properly, and hair loses its natural movement and bounce.
Australian conditions accelerate this process. Sydney and Melbourne's hard water creates mineral interactions with silicones that form even more stubborn residues. Brisbane and Darwin's humidity drives heavier use of anti-frizz products (typically high in silicones), speeding accumulation. Coastal salt exposure compounds the coating effect.
Scalp impact often goes unnoticed. Silicone migration to the scalp can disrupt natural oil regulation, causing either overproduction (compensating for the barrier) or tightness and dryness (blocked hydration). For sensitive scalps, residue may worsen irritation.
How to Identify Silicones in Your Products
Understanding which silicones you're using helps you choose appropriate removal methods and make better product decisions.
Non-Water-Soluble Silicones (require intensive removal):
- Dimethicone: Most common, creates waterproof coating
- Cyclomethicone: Volatile but still accumulates in humid climates
- Amodimethicone: Binds strongly to damaged areas, hardest to remove
- Dimethiconol: Heavy variant used in intensive treatments
Water-Soluble Silicones (easier to remove):
- PEG-Dimethicone: Modified to dissolve in water
- Lauryl Methicone Copolyol: Rinses more easily
Identifying them: Look for ingredients ending in "-cone," "-conol," or "-siloxane" in the first 5-7 ingredients. Multiple silicones listed early indicate heavy accumulation potential.
10 Proven Methods to Remove Silicone from Hair
1. Clarifying Shampoo with Sulfates
Why it works: Sodium lauryl sulfate and sodium laureth sulfate are anionic surfactants strong enough to emulsify and remove non-water-soluble silicones.
How to use: Apply to dry or damp (not soaking wet) hair. Work through from roots to ends, let sit 2-3 minutes, rinse thoroughly. Repeat if needed. For heavy buildup, use 2-4 times over one week.
Australian note: Hard water reduces effectiveness. Extra wash may be needed in Sydney and Melbourne.
2. Sulfate-Free Clarifying Shampoo
Why it works: Strong non-sulfate surfactants like olefin sulfonates remove silicones while being gentler than traditional sulfates.
How to use: Apply to damp hair, massage well, let sit 2-3 minutes, rinse completely. May need 1-2 additional washes compared to sulfate versions.
Best for: Color-treated or chemically processed hair needing silicone removal without harsh stripping.
3. Baking Soda Clarifying Paste
Why it works: High pH (around 9) breaks down silicone coatings, mild abrasiveness provides gentle exfoliation.
How to use: Mix 1-2 tablespoons baking soda with water to form paste. Apply to damp hair, massage 1-2 minutes, leave 3-5 minutes maximum. Rinse thoroughly, follow with regular shampoo.
Caution: Use maximum once every 2-3 weeks. ALWAYS follow with acidic rinse or deep conditioning to restore pH balance.
4. Apple Cider Vinegar Rinse
Why it works: Acidity (pH ~3) dissolves some silicone residues and restores hair's natural pH balance.
How to use: Mix 1-2 tablespoons raw ACV with 1 cup water. After shampooing, pour over hair, let sit 1-2 minutes, rinse with cool water.
Reality check: Works best for light buildup or maintenance. Won't remove heavy dimethicone accumulation alone.
5. Bentonite Clay Mask
Why it works: Negative ionic charge attracts and binds to buildup, drawing silicones from hair shaft.
How to use: Mix 2-3 tablespoons clay with water or ACV to form paste. Apply to damp hair, cover with shower cap, leave 15-20 minutes. Rinse thoroughly, follow with deep conditioner.
Best for: Monthly deep detox, particularly effective for thick, coarse hair.
6. Chelating Shampoo Treatment
Why it works: Targets mineral buildup from hard water that combines with silicones to create more stubborn residues.
How to use: Apply chelating shampoo to wet hair, massage into scalp and lengths, let sit 3-5 minutes, rinse completely. Use every 2-4 weeks in hard water areas.
Australian essential: Critical for Sydney, Melbourne, Adelaide where mineral content is high.
7. Micellar Water Pre-Treatment
Why it works: Micellar technology uses tiny oil molecules suspended in water to attract and lift silicone coatings.
How to use: Saturate hair with micellar water before shampooing. Massage through lengths, let sit 5 minutes, then proceed with clarifying shampoo.
Best for: Fine hair needing gentle but effective buildup removal.
8. Deep Cleansing Oil Method
Why it works: Pre-shampoo oil treatment helps break down silicone bonds, making clarifying shampoo more effective.
How to use: Apply lightweight oil (grapeseed or jojoba) to dry hair, massage 5 minutes, add small amount of water to emulsify, then shampoo 2-3 times with clarifying formula.
Note: This loosens silicones; the shampoo removes them. Oil alone won't eliminate buildup.
9. Lemon Juice Clarifying Rinse
Why it works: Natural acidity cuts through residues and brightens hair.
How to use: Mix juice of 1 lemon with 1 cup water. After shampooing, pour over hair, let sit 2-3 minutes, rinse with cool water. Follow with moisturizing conditioner.
Caution: Can be drying. Use maximum once every 2 weeks.
10. Weekly Maintenance Detox Routine
Why it works: Prevents significant accumulation by regularly removing light buildup.
Routine: Week 1: ACV rinse. Week 2: Clarifying shampoo. Week 3: ACV rinse. Week 4: Chelating treatment. Adjust frequency based on product use and water quality.
Best for: Maintaining silicone-free hair after initial deep cleanse.
Essential Aftercare Following Silicone Removal
Why aftercare is critical: Silicones mask hair's true condition. Removal reveals actual texture, often dehydrated or damaged. Without proper conditioning, hair feels worse, driving people back to silicone products.
Immediate Treatment (First 24 Hours)
Apply rich, protein-free deep conditioning mask after final clarifying wash. Look for shea butter, coconut oil, argan oil, aloe vera, or glycerin. Leave on 15-30 minutes with heat (warm towel). Rinse with cool water to seal cuticle.

Switch to sulfate-free, silicone-free shampoos. Hair Folli's Natural Hair Growth Shampoo uses botanical cleansers that maintain scalp health without harsh sulfates or pore-clogging silicones.
Condition after every wash. Deep treatment weekly. Oil treatments weekly (argan or jojoba for fine hair; coconut or olive for thick hair).
Australian climate adjustments:
- Humid areas (Brisbane, Darwin): Lightweight water-based leave-ins
- Dry areas (Perth, inland): Richer butter-based treatments
- Hard water areas (Sydney, Melbourne): Acidic rinses to prevent mineral buildup
How to Prevent Future Silicone Buildup
Product Selection
Read labels for "-cone," "-conol," or "-siloxane" suffixes. Prioritize:
- Leave-in products without heavy silicones
- Heat protectants with water-soluble alternatives
- Silicone-free or PEG-modified silicone products
- Clean beauty and curly girl method-approved ranges
Washing Technique
Focus shampoo on scalp, massage 60-90 seconds. Rinse twice as long as you think necessary (incomplete rinsing leaves residue). Final rinse with cool water seals cuticle.
Frequency Management
Most people maintain healthy hair washing 2-3 times weekly. In humid climates, more frequent washing may be needed, but focus on scalp cleansing rather than product overload.
Maintenance Schedule
Gentle clarifying every 2-4 weeks prevents accumulation from hard water minerals, pool chlorine, ocean salt, and environmental pollution. In hard water areas, alternate between clarifying (removes product) and chelating (removes minerals) treatments.
Scalp-First Philosophy
A balanced scalp produces optimal natural oils, reducing product dependence. Hair Folli's Growth Shampoo and Conditioner system supports scalp health while excluding silicones, sulfates, and buildup-causing ingredients.

Frequently Asked Questions
Clarifying shampoos containing sulfates or strong surfactants remove silicones most effectively. For heavy buildup, expect 2-4 clarifying sessions over 1-2 weeks. Natural alternatives like baking soda paste work but require careful pH management. The method depends on buildup severity and hair condition.
Complete removal takes 1-2 weeks with consistent clarifying (2-4 treatments total). Light water-soluble silicone buildup may clear in 1-2 washes. Heavy dimethicone accumulation from years of use needs 4-6 sessions. Adjustment period continues 2-4 weeks as hair adapts to functioning without silicone coating.
Yes, temporarily. Silicones mask true hair condition with artificial smoothness. Removal reveals actual texture, often rough or dry. This is normal, not damage. Expect 1-2 weeks adjustment where intensive conditioning is essential. By weeks 3-4, properly moisturized hair typically feels healthier than under silicone buildup.
Yes, using sulfate-free clarifying shampoos with strong surfactants like olefin sulfonates, or natural methods like baking soda paste. These require 1-2 additional washes compared to sulfate versions. Key: silicone removal needs enough cleansing power to break water-resistant coating. Gentle everyday shampoos won't remove established buildup.
Choose clarifying shampoos labeled "buildup removal" or "deep cleansing" containing sulfates or strong surfactants. Ensure the product itself is silicone-free. For hard water areas (Sydney, Melbourne, Adelaide), look for formulas that work effectively despite mineral content. After clarifying, switch to silicone-free maintenance like Hair Folli's Natural Hair Growth Shampoo.
Silicone isn't structurally damaging, but buildup creates problems. Accumulated layers prevent moisture and nutrient penetration, trap dirt and pollutants, make hair progressively dull and heavy, and mask underlying damage. Water-soluble silicones used occasionally pose less risk. Heavy non-water-soluble silicones in daily products typically cause problematic accumulation requiring regular clarifying.
No. Oils cannot dissolve silicones despite seeming similar. Silicones are water-resistant synthetic polymers with different molecular structure than natural oils. Coconut oil or olive oil applied to silicone buildup only adds another coating layer. Actual removal requires surfactants (clarifying shampoos) or alkaline substances (baking soda) that break down silicone molecules.
Conclusion
Silicone removal requires the right method for your buildup level, thorough aftercare during the adjustment period, and sustainable prevention strategies. The process isn't instant, but within 2-4 weeks, most people achieve lighter, more responsive hair that absorbs products effectively and displays its natural texture.
The key insight: removal is half the solution. Without addressing why you used silicone products initially (frizz, dryness, damage), you'll restart the buildup cycle. A scalp-first approach focusing on genuine hair health, proper moisture balance, and clean formulations prevents this pattern.
For Australian conditions specifically, hard water and humidity create enough challenges without product buildup. Clean, lightweight formulations like Hair Folli's range work with our climate rather than against it, supporting both scalp and hair health sustainably.
