In a nutshell
- ✨ How it works: chamomile (rich in apigenin and quercetin) adds golden hues while baking soda’s mild alkalinity briefly lifts the cuticle—a gentle brightening, not bleach-level lightening.
- 🧪 Method and ratios: Brew strong tea (3–5 bags/250 ml), mix with 2–3 tbsp baking soda to a yogurt-like paste, apply 10–30 minutes, then use an acidic rinse and conditioner; always patch/strand test first.
- 🕒 Results to expect: Gradual, cumulative brightening of about ½ to 1 shade; indirect sun or controlled heat can subtly amplify effects without harshness.
- 🧴 Suitability and tone control: Best on light brown to dark blonde; darker hair gains warmth and sheen; manage brass with a brief purple conditioner if needed.
- ⚠️ Care and cautions: Limit frequency (weekly or less), avoid use on freshly coloured or very damaged hair, and prioritise moisture/protein balance to keep porosity and shine in check.
As salon budgets tighten and eco-minded beauty gains pace, a gentle at-home brightening blend has resurfaced: chamomile paired with baking soda (bicarbonate of soda). This low-cost duo coaxes out warm, sunlit tones without the sharp punch of bleach. The herbal tea brings golden pigments and UV-reactive polyphenols; the alkaline powder nudges the cuticle ajar so light and infusion can do their work. It will not deliver platinum transformations, but it can soften brunettes, lift dull blonde, and add honeyed glow to light brown hair. Used carefully, it’s a measured route to lift colour while keeping texture in focus and damage in check.
Why Chamomile and Baking Soda Lighten Hair
Chamomile contains apigenin and quercetin, plant compounds that deposit a subtle golden tone and interact with light. Sun or blow-dryer warmth can amplify this effect, echoing the “lemon-and-sun” folklore but with a softer touch. Baking soda—properly, bicarbonate of soda—is mildly alkaline (around pH 8–9). It does not bleach; instead it briefly lifts the cuticle, letting the chamomile infusion reach superficial pigment and reflect more light. Think of it as encouraging brightness and warmth rather than stripping colour.
Because alkalinity increases hair’s porosity, the mixture can hasten the fading of darker dyes and accentuate underlying warm tones already present in many European hair types. On virgin hair, you’ll often see a half-shade to one-shade lift across multiple uses. On highlighted hair, it can soften regrowth lines. What it won’t do is push past your hair’s natural depth like peroxide, which is why expectations and patience are essential. Follow with acidic care to rebalance pH and retain slip.
Method, Ratios, and Timing
Start with a strong brew: steep 3–5 bags of chamomile (or 2 tablespoons loose flowers) in 250 ml hot water for 10 minutes; cool fully. In a bowl, combine 2–3 tablespoons baking soda with enough tea to form a yogurt-like paste. Apply to clean, damp hair from mid-lengths to ends, then to roots. Comb through for even distribution. Leave 10–30 minutes, checking every 5–10 minutes for feel and tone. Always patch test on skin and a hair strand 48 hours in advance.
Rinse thoroughly, then use a mild acidic rinse (1 teaspoon apple cider vinegar in 250 ml water) to help seal the cuticle, followed by a moisturising conditioner. Limit use to once a week, or fortnightly for fine or porous hair. If you plan to be outdoors, allow hair to dry naturally in indirect sun, which can amplify chamomile’s reflectivity; otherwise, a cool blow-dry helps set the effect without extra roughness.
| Variable | Recommended Range | Purpose | Notes |
|---|---|---|---|
| Brew strength | 3–5 bags per 250 ml | Maximises golden pigments | Cool fully before mixing |
| Baking soda | 2–3 tbsp | Raises pH to lift cuticle | Too much can feel gritty/drying |
| Exposure time | 10–30 minutes | Controls lift intensity | Check every 5–10 minutes |
| Frequency | Weekly or less | Gradual, cumulative lightening | Reduce for fragile hair |
| Aftercare | Acidic rinse + conditioner | Rebalances pH, adds slip | Optional protein mask monthly |
Suitability, Results, and Aftercare
On light brown to dark blonde hair, expect a warm brightening that reads “sun-kissed.” Medium to dark brown hair sees softer warmth and reflective sheen rather than dramatic lift. Grey and very coarse hair may respond unevenly due to tight cuticles. Colour-treated hair, especially with red or violet dyes, can skew brassy as alkalinity exposes underlying warmth; strand test first. Avoid use on severely damaged, over-processed, or freshly coloured hair within two weeks, as porosity can spike and feel rough.
Post-rinse, focus on balance. A humectant conditioner (look for glycerin or aloe) restores moisture, while an occasional light protein (hydrolysed wheat or rice) supports strength without stiffness. Seal with a few drops of oil on ends. Space applications to let hair recover and monitor progress under natural light. If brass creeps in, a gentle purple conditioner used briefly can cool the tone without overwhelming chamomile’s softness. Healthy hair always looks lighter because it reflects more light, so shine care is as vital as the recipe.
Chamomile with baking soda is the slow journalism of hair colour: steady, transparent, and respectful of the fibre. The science is humble—polyphenols, pH, and light—yet the result can be quietly persuasive, especially on hair already flirting with blonde. Keep ratios moderate, keep aftercare consistent, and keep expectations realistic. If you want lift without the harshness of bleaches and box dyes, this botanical-alkaline duet can be your gentle middle ground. Will you try a strand test and chart your tone shift over a month to see how your hair responds?
