Aging causes significant changes to hair, including loss of pigment, decreased density and shine. Although gray hair is a pure sign of aging, it is not desired by everyone. The good news: It is possible to keep gray hair looking healthy and shiny.
Thus, more and more people are using natural treatments to hide or tone gray hair. These remedies seek to reduce the use of harsh chemicals.
This is where this simple and effective combination comes into play, which the medium Herald brought us to memory. The baking soda and rosemary mixture It has become popular for its properties to strengthen hair and progressively darken gray hair. Baking soda balances the pH of the scalp, while rosemary acts as an antioxidant, stimulating melanocytes and improving hair hydration.
Preparation and application of treatment
The remedy is simple to prepare with basic ingredients: water, rosemary and baking soda. The mixture is made by boiling a liter of water with several sprigs of fresh rosemary, as well as three tablespoons of baking soda. Let it cool and apply it to the hair like a dye, covering from roots to tips.
It is worth clarifying that, although there are no scientific studies that support the effectiveness of this remedy, numerous individual testimonies suggest its benefits. The advice is to use it in moderation and consider that the results may vary from person to person.
Properties of these ingredients
Baking soda and rosemary can help hair, especially by cleansing the scalp and stimulating growth, but baking soda should be used very little because it can be drying and damaging.
Properties of baking soda
- It is an alkaline compound with a strong cleansing effect, capable of removing grease, product residues and dead cells from the scalp.
- It can specifically balance the pH of the roots, helping the hair to better absorb active ingredients of pure origin and look cleaner and lighter.
- Used in excess, it alters the pH of the scalp and can cause dryness, irritation and weakening of the hair, which is why it is recommended only occasionally.
Rosemary properties
- Rosemary contains antioxidants (such as caffeic and rosmarinic acids) and anti-inflammatory compounds that improve microcirculation in the scalp.
- By stimulating blood circulation, it can promote hair growth, strengthen the follicle and help reduce hair loss.
- It has antimicrobial and antifungal action, which helps control dandruff and keep the scalp healthier.
- In brown or dark hair, the constant use of rosemary infusions or oil can slightly darken the tone and improve shine and texture.
Benefits for hair (each and together)
- Deep cleansing: baking soda works almost like a gentle “peel”, eliminating fat and impurities that weaken the follicle, while rosemary provides freshness and antimicrobial properties.
- Less hair loss and better growth: rosemary stimulates circulation and follicle regeneration, and having a clean scalp (thanks to occasional baking soda) promotes healthier growth.
- Shine and texture: Several sources point out that the mixture can leave hair shinier, stronger and healthier looking, especially if rosemary is used constantly and baking soda only occasionally.
- Gray hair and shade: the idea has become popular that rosemary + baking soda helps to “hide” or tone gray hair, better maintaining the pure shade and giving more luminosity to the hair; However, scientific evidence is limited and should be taken as a cosmetic trick rather than medical treatment.
How to use it more safely
- Frequency: If you decide to use baking soda, do it occasionally (for example, once every 2–3 weeks) and not as a daily substitute for shampoo, to avoid dryness and irritation.
- Typical way of use: an infusion of rosemary is usually prepared (branches in hot water) and a small amount of baking soda is mixed; Apply to the scalp with a gentle massage and rinse thoroughly, followed by a moisturizing conditioner.
- Hair type: in very dry hair, with chemical damage or lustrous scalp, it is advisable to avoid baking soda and only use rosemary infusion or oil, which is less aggressive.
- General caution: If you notice itching, intense dryness, increased hair loss or irritation, discontinue use and return to gentler care, ideally consulting a dermatologist.
