Does Baking Soda Work on Gray Hair? Evidence on Using Baking Soda for Gray Coverage

Using Baking Soda to Address Gray Hair

Baking soda is a versatile household staple with a variety of uses. Some people claim baking soda can help cover up gray hair or slow further graying. However, there is limited research on baking soda's ability to affect gray hair. This article explores the evidence, risks, and alternatives for using baking soda on graying hair.

How Baking Soda Could Impact Gray Hair

Baking soda, otherwise known as sodium bicarbonate, is a chemical salt compound with a crystalline appearance. It has mild abrasive and antiseptic properties that account for many household and personal care uses. Some ways baking soda could potentially influence gray hair include:

• Binding to hair proteins - Natural hair color comes from melanin pigments. Baking soda may bind to melanin and partially cover gray hairs.
• Cleansing action - Baking soda helps remove dirt, debris, and product buildup that can make grays look yellow.
• pH effect - Baking soda is alkaline. Opening hair cuticles could allow more deposition of temporary color.
• Mild abrasion - Gently scrubbing with baking soda loosens dead cells and debris on the hair and scalp surface.

However, there is no definitive research proving baking soda can reverse graying or provide lasting color effects. Any color change is likely temporary and superficial.

Using Baking Soda on Gray Hair

Those wishing to test baking soda's effects on grays can try the following methods:

• Baking soda shampoo: Mix 1 teaspoon baking soda into palmful of shampoo; apply thoroughly to wet hair; rinse.
• Baking soda rinse: Stir 1 teaspoon baking soda into 1 cup warm water; pour over hair after shampoo; leave on 2-3 minutes; rinse.
• Baking soda scrub: Dampen hair; gently massage a sprinkle of baking soda directly into scalp for 2-3 minutes; rinse.

Use no more than once or twice per week to avoid excessive drying or irritation. People with hair color should avoid baking soda, which can strip permanent pigments.

Evidence for Baking Soda and Gray Hair

There are two main types of scientific studies on baking soda's effects on hair:

• Animal studies: Rat research found topical baking soda and water reduced hair melanin content compared to distilled water after 4 weeks. However, animal studies don't always apply to human hair.
• Human hair studies: Research shows baking soda cleanses hair. A study of baking soda shampoos found they can slightly lighten artificial gray hair color. But data on real human gray hair is lacking.

Overall, the research suggests baking soda may have a minor cleansing effect on gray hairs by removing dirt, oil, and protruding cuticle cells. This surface debris can make gray strands appear darker or yellowed. But there's no solid proof it reverts gray hair.

Risks of Using Baking Soda on Hair

While baking soda is generally recognized as safe for household use, overuse comes with some risks. Potential side effects of baking soda hair treatments include:

• Dry, brittle hair
• Scalp irritation
• Damage to color-treated hair
• Hair breakage
• Loss of elasticity and shine

These effects stem from baking soda's alkaline pH and ability to disrupt the protective cuticle layer. With frequent use, the cuticle can lift and allow moisture loss. For those with gray hair, this can worsen a dry, wiry texture.

To limit damage, avoid over-scrubbing and maintain a neutralizing, moisturizing hair care routine. Discontinue baking soda if irritation occurs.

Other Natural Approaches for Gray Hair

In addition to baking soda, some natural methods for covering or blending in gray hairs include:

• Lemon juice: May deposit temporary yellow pigment.
• Chamomile tea: Rinsing with cooled tea adds golden highlights.
• Henna dye: Provides reddish-brown semi-permanent color.
• Essential oils: Rosemary and sage oils could help cleanse and darken hair.
• Anti-gray supplements: Some supplements like catalase, copper, and fo-ti may help marginally.
• Curry leaves: Used in some cultures to impart subtle warming color.

However, these home remedies have limited research backing their efficacy and safety. Consult your doctor before using unproven supplements.

Salon Options for Covering Grays

For those seeking longer-lasting gray coverage, professional salon solutions include:

• Semipermanent rinses: Deposit temporary opaque color that washes out over 4-6 weeks.
• Permanent dye: Chemically alters hair structure for long-lasting color that grows out with new growth.
• Lowlights/highlights: Strategic application of color weaves in darker or lighter pieces to blend grays.
• Bleaching: Lightens hair to create an all-over monotone that masks gray.

To find the most natural-looking results, select a colorist experienced in blending gray hair. Maintenance is needed as new growth appears.

Medical Options for Gray Hair

Those concerned about the time and cost of continual dyeing may consider medical gray hair solutions, such as:

• Prescription topicals: Creams that gradually reduce melanin production in new hair growth.
• Laser caps: Low-level laser treatment that may help hair follicles produce melanin.
• Micropigmentation: Tattooing that colors the scalp with natural-looking pigments.

These options may not reverse existing gray hair. But they can potentially blend in new growth without frequent salon visits. See a dermatologist to weigh their safety and results for your situation.

When to See a Doctor

Sometimes seemingly normal graying signifies an underlying health issue. It's a good idea to consult a doctor or dermatologist if you experience:

• Sudden graying before age 30
• Rapid graying over a few months
• Gray hair confined to one section
• Other pigment changes like vitiligo
• Accompanying symptoms like fatigue or weight changes

A physician can check for conditions like vitamin deficiencies, thyroid disease, autoimmune disorders, and vitiligo. Addressing underlying causes may improve related symptoms and cosmetic effects.

Caring for Graying Hair

To keep gray strands looking their best, consider:

• Using sulfate-free, color-safe shampoos
• Conditioning to add moisture and manageability
• Brushing gently with a detangling tool
• Avoiding heat styling to limit damage
• Using cool water instead of hot
• Working in nourishing oils before washing
• Getting regular trims to limit split ends

Keep in mind gray hair tends to be drier. Adjust your hair care routine accordingly to prevent a coarse, wiry, frizzy texture.

Key Takeaways

• Some claim baking soda can help cover up gray hairs, but proof is limited.
• It may temporarily cleanse and remove yellow tones from grays.
• Overuse risks drying, breakage, irritation, and stripping color-treated hair.
• Natural approaches like lemon, chamomile, oils, henna, and supplements may help, but safety and efficacy vary.
• See a doctor for sudden graying, rapid graying, or grays with other symptoms.
