To detox your hair from silicones, wash with a clarifying shampoo, applied to the scalp and worked down the lengths, then condition the mid-lengths and ends. Repeat on a schedule, not every wash. Silicones that don’t dissolve in water can stack up on the hair shaft. A rinse with water won’t move them, but a proper cleanse will. Then you rebuild a routine that keeps buildup from returning. If you want a scalp-first routine from a brand built around it, CRISAN’s shampoos and conditioners are a good place to start.
TL;DR
- Non-soluble silicones (dimethicone, amodimethicone) can build up over time. Soluble and evaporating ones are much less likely to.
- Signs: hair that feels dirty after washing, looks limp, dull or coated, or has a faint white film.
- A clarifying shampoo is the removal step. Using one every 2 to 3 weeks is a common trichologist recommendation if you use silicones.
- Condition after every clarifying wash. Focus shampoo on the scalp and be gentle with wet hair.
- Itch, flaking or redness that persists is not always buildup. See a dermatologist.

What silicones do in hair products
Silicones are conditioning ingredients. The U.S. Trichology Association describes them as forming a thin film on the hair fiber that lowers friction, eases combing and adds shine. They are not villains. The same source notes that the Cosmetic Ingredient Review panel concluded dimethicone and related ingredients are safe as used in cosmetics.
The issue is accumulation. A comprehensive review of silicones in hair care notes that prolonged use of water-insoluble silicones such as dimethicone can lead to buildup on the hair shaft. Buildup is a cosmetic issue, not a health emergency. It shows up as hair that is limp, coated or dull, and you manage it with the way you cleanse.
Three kinds of silicone
Not every silicone behaves the same way. InStyle’s expert roundup breaks them down like this:
| Type | Examples | What it does |
|---|---|---|
| Non-soluble | Dimethicone, amodimethicone | Long-lasting, water-resistant barrier. Removed only with sulfates or a clarifying shampoo. Can build up over time. |
| Soluble | Names with PEG, such as PEG-12 Dimethicone | Washes out with water. |
| Evaporating | Cyclomethicone | Leaves a dry finish. Least likely to cause buildup. |
The same article says ingredients ending in -cone, -siloxane or -conol are likely silicones. Check the ingredient lists of your shampoo, conditioner, leave-in, heat protectant and styling products. The ones to watch are the non-soluble kind, especially if several of your products contain them.
How to tell if you have silicone buildup
There is no lab test you need at home. Look for patterns:
- Your hair feels dirty or heavy even right after washing.
- A subtle white film shows on the strands.
- Hair looks flat at the roots and dull along the lengths.
- Conditioner seems to stop working. InStyle’s experts explain that a coating can keep conditioning agents from penetrating, and that over time buildup can make hair frizzier.
If you use silicone products regularly and notice the first sign above, buildup is a likely cause. Other products stack up too: dry shampoo, hairspray, heavy oils and styling creams. A detox clears all of them, not just silicones.
Hard water minerals can leave a similar dull, stiff feel. If your water is hard, read our guide to chelating hard water hair. For a deeper look at the signs, see our article on silicone buildup in hair.
How to detox your hair from silicones, step by step
1. Check your labels first
List every product you use in a week. Mark the ones with non-soluble silicones. This tells you how heavy your buildup load is and what you may want to swap out later.
2. Choose a clarifying shampoo
Research is clear on the mechanism. A 2018 study on cleansing conditioners found that non-soluble silicones deposit along the fiber and under the cuticle scales, and that frequent use of them calls for regular use of sulfate surfactants to avoid residue. Clarifying shampoos are built to do this deeper cleansing job. Pick one for your hair type, and read the label for the ingredients you prefer.
3. Wash the scalp, not the whole length
The American Academy of Dermatology recommends applying shampoo to your scalp rather than the entire length of your hair. That way you wash away built-up product, dead skin and excess oil without drying out the lengths. Massage with your fingertips, not your nails. Let the suds run down the hair as you rinse. If your hair is very coated, a second light lather on the scalp is fine.
4. Condition the mid-lengths and ends
Clarifying can leave hair feeling squeaky. The AAD advises using conditioner after washing to moisturize and detangle, and being gentle with hair when it’s wet. Comb with a wide-tooth comb or a soft brush, starting at the ends.
5. Rebuild the routine
A detox only helps if the buildup doesn’t return at the same speed. The review of silicones in hair care advises that you alternate between silicone-based and silicone-free products and use clarifying shampoos periodically, especially if your hair is fine or oily. That keeps residue down without harming the hair.
How often should you clarify?
If you use silicone products, trichologist Oropeza told InStyle that clarifying every 2 to 3 weeks works, balanced with non-silicone products. Use that as a starting point:
- Fine or oily hair, daily styling products: the shorter end of that range.
- Dry, coarse or curly hair: the longer end, with a rich conditioner after.
- Mostly silicone-free routine: you may rarely need a full detox.
More is not better. The silicone review warns that excessive use of sulfate clarifiers may cause dryness or cuticle damage. Pay attention to how your hair feels a day later, and stretch the interval if it feels dry or rough.
A note on co-washing
Co-washing means cleansing with conditioner only. It is gentle, and it suits some hair, but it does not remove non-soluble silicones. The 2018 cleansing conditioner study says non-soluble silicones cannot be removed by the nonionic surfactants in co-washing products. It also says co-washing is suitable only for people with minimal buildup, is not adequate if you regularly use silicone-based styling products, and should be paired with a clarifying shampoo every 15 days.
If you co-wash and your hair feels weighed down, a clarifying wash is the fix.
What about DIY detoxes?
Apple cider vinegar rinses are the most popular home remedy. A Nebraska Medicine dermatologist says ACV is not a magic topical and that, if you’re healthy and want to try it, moderation is the rule. Because it is acidic, the same source advises diluting it, starting with half a tablespoon per eight ounces of water. Too much can cause skin problems, brassiness and even burns. If you have a skin condition, the dermatologist would not recommend it.
Rinses are an add-on, not a substitute for a proper clarifying shampoo. Keep any acidic rinse away from irritated or broken skin.
When it isn’t buildup: scalp symptoms
A detox cleans product residue, oil and dead skin. It will not treat a scalp condition. A systematic review of scalp itch lists many possible causes of itching with scaling or redness, including seborrheic dermatitis, scalp psoriasis, contact dermatitis, tinea capitis and dry skin linked to eczema or aging. Some of these need diagnosis and prescription care.
See a dermatologist if you have:
- Itching that continues after you clarify and change products
- Thick scale, redness, burning or sores
- Patchy hair loss
If your scalp feels congested rather than inflamed, our guide on sebum plugs on the scalp explains how they differ from buildup, dandruff and psoriasis, and when to see a dermatologist or trichologist.
Our point of view
We started CRISAN after our founder’s own struggle with postpartum hair loss. That taught us to look at the scalp first, because healthy hair grows from a clean, cared-for scalp.
Hair detoxing should be simple and honest. Silicones are not something to fear. They are an ingredient that needs a cleansing plan. Build a routine you can keep: cleanse on a schedule, condition well and give hair a break from heavy layering.
Our products are made in the USA from a blend of 55 botanical ingredients, inspired by generations of Ayurvedic tradition. They are vegan and suitable for all hair types. We make no unrealistic promises. We give you tools and education to build healthier routines for the long term.

FAQ
Can silicone buildup damage my hair?
Buildup itself is a cosmetic issue. It can leave hair coated, limp or dull and can block conditioner. Over-cleansing with harsh clarifiers is the bigger risk to the cuticle, so clarify on a schedule and condition afterward.
How do I get rid of silicone buildup in my hair?
Use a clarifying shampoo on your scalp and rinse it through the lengths. Follow with conditioner on the mid-lengths and ends. Repeat every 2 to 3 weeks if you use silicone products, and alternate silicone-based and silicone-free products between washes.
How do I know if a product has silicones?
Look for ingredients ending in -cone, -siloxane or -conol, such as dimethicone or amodimethicone. Names with PEG, like PEG-12 Dimethicone, are water-soluble and rinse out more easily.
Is a scalp detox the same as a silicone detox?
They overlap. A scalp detox removes sebum, dead skin cells and product. A silicone detox targets coating along the hair. One clarifying wash does both. Persistent itching or flaking calls for a dermatologist.
