deodorizing hair and scalp

deodorize the hair and scalp

eliminate odors from the hair and scalp quickly and gently with this step by step method using readily available tools and products

getting rid of odor from hair and the scalp is trickier than getting rid of body odor

bacteria in the scalp and in the hair shaft can be difficult to reach and kill without damaging the hair

the cause of smelly hair and scalp can be

  • internal such as diet or metabolism
  • external such as microbe wastes
  • a combination of both

this method deodorizes external causes of hair and scalp odor

tools to deodorize smelly hair: isopropyl alcohol 99%, oregano oil, water, clean towel, coconut oil, tea tree oil, sulfate-free shampoo, conditioner, anti-fungal shampoo, hair dryer
tools to deodorize smelly hair
isoproyl alcohol rapidly kills bacteria, fungus, parasites and viruses at a conentration of 60-90%
isopropyl alcohol

isopropyl alcohol

isopropyl alcohol is inexpensive and widely available in pharmacies and general stores

alcohol is rapidly antimicrobial at a concentration range of 60-90%

any concentration below 60% is too weak to eliminate many microbes

while above 90% is too strong and won’t penetrate the microbe protein layer

pure isopropyl alcohol at 99-100% is the most readily available strength and should be diluted with water prior to use

example dilutions

  • 40ml water + 60ml pure isopropyl alcohol makes 100ml of 60% isopropyl alcohol
  • 40ml water + 80ml pure isopropyl alcohol makes 120ml of 67% isopropyl alcohol
oregano oil is a powerufl antibacterial antifungal antparasitic antiviral antimicrobial to treat smelly hair
oregano oil

oregano essential oil

oregano essential oil is a broad spectrum anti-microbial product

the main active compounds are carvacrol and thymol

  • carvacrol is an antioxidant and anti-inflammatory
  • thymol is anti-microbial and effectively kills fungal spores

oregano essential oil can be purchased from health stores


  • undiluted oregano oil can burn skin
  • excessive use of this oil may increase estrogen activity in the body
tap water can be used to deodorize smelly hair and scalp, bad breath, underarm odor, smelly genitals, smelly feet and whole body odor


tap or bottled water can be used to dilute isopropyl alcohol to 60-90%

coconut oil

coconut oil

coconut oil is an ideal inexpensive hair moisture treatment

unlike other oils it penetrates the hair shaft and doesn’t support microbe growth

coconut oil odor can be unpleasant to some people and can take several washes to remove from fabrics

to overcome this deodorized coconut oil is an effective alternative

antifungal antibacterial antiparasitic antiviral antimcrobial tea tree oil is effective at preventing microbial infection of the hair and scalp
tea tree oil

tea tree oil

tea tree oil is a broad spectrum antimicrobial

the main compounds of tea tree oil are terpenes

terpenes are very effective insect repellents and are anti-parasitic

tea tree oil can be purchased at online retailers, supplement stores, supermarkets and pharmacies


  • tea tree oil is a phyto-estrogen and excessive use can mimic estrogen effects in the body
use a sulfate free shampoo and conditioner to avoid irritating the scalp and over-stripping the hair
sulfate free shampoo and conditioner

sulfate free shampoo and conditioner

alkaline and sulfate shampoos can excessively dehydrate the scalp

a dry alkaline scalp secretes more sebum to correct the imbalance and this creates excess oils, proteins and lipids which can lead to smelly odors

gentle, sulfate-free, pH balanced shampoos and conditioners minimizes disruption to the scalp pH and moisture levels

this in turn keeps secretions at an ideal level for a healthy odor-free scalp

washing more often with gentle products is better for scalp health than washing with harsh shampoos

always use a clean dry towel after deodorizing to prevent recontamination
clean dry towel

clean towel

use a clean dry towel after every wash to prevent re-contamination while deodorizing the hair and scalp

use a hairdryer to dry the hair quickly in humid environments to discourage reconatmination of damp hair
hair dryer

hair dryer (optional)

wet hair will dry very slowly in a humid environment

in this case a hair dryer should be used to prevent microbe growth

antifungal shampoo can be used to kill off chronic fungal infections that may be causing smelly hair or scalp
anti-fungal shampoo

anti-fungal shampoo (optional)

stubborn or extensive dandruff can be treated with anti-fungal shampoo to speed up the odor elimination process

use ketoconazole 2% shampoo twice per week instead of your normal shampoo until dandruff is resolved

anti-fungal shampoo can be purchased from a local or online pharmacy

ketoconazole is an anti-fungal medication shown to be poorly absorbed through the skin and is therefore considered a relatively safe topical treatment

anti-fungal shampoos have also shown to improve hair growth in some people


prepare treatments

anti-microbe hair and scalp spray

this anti-microbe spray will kill all microbes and spores

  • 80ml isopropyl alcohol 99%
  • 40ml water
  • 30 drops oregano essential oil

add all ingredients into a spray bottle

shake well before use

anti-microbe hair recovery mask

this recovery mask re-hydrates hair after using the anti-microbe spray

  • 50 grams coconut oil
  • 20 drops tea tree oil

place ingredients into a small jar or dish and mix well

deodorize internally

before deodorizing the hair and scalp it is recommended to complete the prepare phase in the steps to eliminate odor

this step minimizes smelly compounds in the body that may be leading to smelly hair and scalp

deodorize accessories

it can also help to deodorize fabrics, tools and accessories that touch the hair to prevent re-contamination

  • pillowcases
  • towels
  • hair ties
  • scarves
  • hats
  • headbands
  • shower caps
  • wraps
  • other

if anything can’t be deodorized or replaced then set it aside for now

deodorize hair and scalp

  1. saturate dry unwashed scalp and hair with the prepared antimicrobial spray
  2. leave for 20 minutes to 1 hour
  3. apply hair recovery antimicrobial mask generously to hair from root to tip
  4. leave for 2 hours to overnight
  5. wash scalp and hair with a gentle sulfate free shampoo, repeat if necessary
  6. condition hair with a nourishing conditioner
  7. ensure hair dries quickly, either naturally or with a hair dryer
  8. repeat every 2-3 days until the odor is resolved


isopropyl alcohol is very drying and so it is very important to apply the hair recovery mask after the hair and scalp spray to avoid damaging hair
