Oily Hair: What It Is and Why It Happens

    Oily hair doesn’t start with your hair at all — it starts with your scalp.

    Your scalp, like the rest of your skin, is covered with thousands of tiny openings called pores. Each pore is connected to a hair follicle — the small structure that anchors each strand of hair.

    Every pore is technically a hair follicle that can produce sebum the natural skin oil

    Attached to most follicles are sebaceous glands, which produce sebum, a natural oil that helps protect and condition both scalp and hair. These glands are especially active on the scalp and face.

    Your hair doesn’t make oil on its own.
    When hair looks greasy, it’s because the sebaceous glands on your scalp are producing more oil than your hair can absorb or distribute.

    For some people, this happens only occasionally. For others, it’s a daily struggle: you wash, dry, and style your hair… and within hours it’s flat, limp, shiny, or heavy. 

    If you have naturally oily skin, you’re more likely to have an oily scalp — oil production is part of your body’s natural balance.

    Why Some People Get Oily Hair

    Many factors influence how quickly your scalp becomes oily. Some are biological, some environmental, and some come down to hair type.

    One of the biggest contributors is hair density. People with fine hair often notice greasiness sooner because fine strands take up less space — meaning more follicles (and more oil glands) per square inch.

    Other common triggers include:

    • Genetics
    • Changing hormones
    • Weather, humidity, and seasonal shifts
    • Stress and overall health
    • Diet and lifestyle habits
    • Product buildup
    • Over conditioning
    • An unbalanced hair care routine

    Signs of Oily Hair

    Oily hair is more than simply needing an occasional wash. Excess oil can change how your hair looks, feels, and behaves throughout the day.

    • Hair looks greasy or shiny soon after washing
    • Hair feels heavy, flat, or weighed down
    • Hair lacks volume and becomes limp or lifeless
    • Hair and scalp feel oily within a day of washing
    • Scalp feels itchy or irritated
    • Product, dirt, and oil build up easily on the scalp and hair

    When excess oil traps dirt, dust, and dead skin cells, it can sometimes irritate the scalp, contribute to flaking or discomfort, or cause blemishes around the hairline. In more persistent cases, clogged follicles and scalp irritation may contribute to increased shedding or thinning over time.

    Helping an Oily Scalp Find Its Balance

    Once you understand what’s happening on the scalp, the next step is choosing products that support—not fight—your natural oil production. The goal isn’t to strip the scalp dry; it’s to bring everything back into balance so your hair feels clean and light for longer. 

    Use a Gentle, Natural Shampoo

    The first step in managing oily hair is choosing the right shampoo.

    Many people reach for “oily hair” shampoos, hoping to dry out the scalp. Unfortunately, harsh detergents do the opposite of what you want. Hair may feel clean at first, but when the scalp becomes overly dry, oil glands often respond by producing even more oil, creating a cycle of over‑washing and over‑producing oil.

    Use a Gentle Natural Shampoo

    A gentler approach works better. Cleansing products made with natural ingredients help remove excess oil and buildup without over-drying the scalp, allowing oil production to gradually rebalance.

    Our natural shampoo bars cleanse effectively while remaining gentle on both hair and scalp.

    Ingredients like citrus essential oils help refresh and clarify oily hair, while soapnuts — rich in natural saponins — provide an extra cleansing boost without harsh detergents. Hair feels clean, light, and manageable without the scalp feeling stripped or irritated.

    If your hair looks and feels best when freshly washed, you can shampoo daily—when using a gentle, natural shampoo bar. Daily washing only becomes a problem when the shampoo is too harsh.

    Clarify and Rebalance with an Apple Cider Vinegar Rinse

    Even with regular washing, excess oil and styling products can gradually build up on hair and scalp, leaving hair feeling heavy and dull.

    Organic ACV Hair Rinse - Summer Rain Scent

    An apple cider vinegar (ACV) rinse can make a noticeable difference for oily hair.

    When properly diluted, apple cider vinegar (ACV) helps dissolve buildup and excess oil without stripping natural moisture.

    Hair feels lighter, the scalp feels refreshed, and residue that can attract dirt and oil is washed away.

    Because apple cider vinegar also naturally helps maintain a healthy scalp environment, many people find it soothing for occasional itchiness or flaking related to oil and buildup.

    Our ACV rinses contain no added water, which means you can customize them to your hair’s needs. A lighter dilution offers a gentle refresh, while a stronger mix helps cut through stubborn oil or buildup. You get to adjust the strength depending on the season, your scalp’s oiliness, or simply how your hair feels that day.

    Infused with certified organic herbs and essential oils chosen to support both scalp and hair, they leave hair feeling clean, soft, and manageable.

    Extend Freshness Between Washes with Dry Shampoo

    Dry shampoo is a helpful way to refresh hair between washes by absorbing excess oil at the scalp, adding body, and helping hair look and feel cleaner.

    Natural Organic Dry Shampoo Powder

    It’s especially useful for busy days or for areas like bangs, which tend to get oily quickly. 

    A small amount can quickly revive hair without needing a full wash.

    While dry shampoo works well as a quick refresh, it shouldn’t replace regular washing.

    Using too much or relying on it for several days in a row can lead to buildup on the scalp and hair, which may clog pores, irritate the scalp, and leave hair feeling heavy and looking dull or stiff.

    For best results:

    • Use a small amount — a little goes a long way
    • Focus application at the roots where oil collects
    • Continue washing hair regularly to keep scalp and hair healthy

    Used occasionally, dry shampoo is a simple way to keep oily hair looking fresh between washes without disrupting your scalp’s natural balance.

    Additional Tips for Managing Oily Hair

    • Wash with lukewarm or cool water; hot water can trigger more oil production.
    • If you use conditioner, keep it away from the scalp and apply only to the ends.
    • Rinse thoroughly to prevent residue that can weigh hair down.
    • Brush your hair before shampooing to help distribute natural oils.
    • Keep your hairbrush clean—old product and oil can transfer right back to your hair.

    Things to Avoid

    Harsh detergent shampoos  
    These can strip the scalp and trigger a rebound effect, causing even more oil production.

    Heavy styling products and excessive heat  
    Thick creams, heavy conditioners, and frequent heat styling can weigh hair down and contribute to greasiness. Frequent heat styling can dry and irritate the scalp, sometimes encouraging excess oil production.

    Constantly Touching or Brushing Hair
    Running your hands through your hair transfers oils and dirt from your fingers onto your strands, making hair look greasy faster. Touching the scalp can also stimulate oil production.

    Brushing too often throughout the day can spread oil more quickly from the scalp down the hair. If hair needs refreshing, brush gently through the lengths and ends rather than the roots.

    In Summary

    Most people with oily hair can find a comfortable balance — not by eliminating oil, but by helping the scalp settle into a healthier rhythm. Oil is natural and necessary; the goal is simply to keep it from overwhelming the hair.

    Some scalps will always produce more oil than others, but with the right routine, gentle products, and a few small habits, almost everyone can reach a place where their hair feels cleaner, lighter, and fresher for longer.

    What Do Herbs Infused In Vinegar Do?

    Why Do We Infuse Herbs Into Our ACV Rinses

    Nature's herbs and botanicals have a life force of their own.
    The vinegar extracts the healing and soothing phytochemicals from medicinal herbs and botanicals.

    Natural Organic Herbal Skin Care Basil, Ocimum basilicum, stimulates hair follicles, increases scalp circulation and promotes hair growth. Basil helps protect hair from breakage, its anti-inflammatory properties help soothe the roots and it adds luster to dull hair.

    Burdock, Arctium lappa, nourishes and strengthens hair follicles, to promote healthy hair growth and improve the condition of hair. It helps soothe irritated scalp conditions, decrease breakage and adds sheen, body & luster. The mucilage in burdock root adds “slip” to hair to make detangling easier.

    Horsetail, Equisetum arvense, is nourishing and hydrating, stimulates the scalp and has been used for centuries as a hair growth herb. The silica in horsetail helps to keep hair strong and adds shine and luster to hair.

    Lavender, Lavendula officinalis, has anti-inflammatory, anti-bacterial and antifungal properties that may help with irritated scalp conditions and hair loss. It helps balance oil production as is a great herb for all hair types.

    Nettle, Urtica dioica, stimulates the scalp, improves circulation, helps decrease breakage and promotes body, bounce, and shine. Nettle hair rinses are an old remedy to help reduce hair loss and encourage hair growth. Nettles balance oil production and help with dandruff.

    Rosemary, Rosemarinus officinalis, encourages the growth of strong healthy hair by improving blood flow to the scalp. The stimulating and revitalizing properties of rosemary help increase manageability, add shine, and condition the hair and scalp.

    Ida's Shampooing Technique for Long Hair

    Ida's Shampooing Technique for Long Hair

    Men and women with short hair seldom have hair adjustment problems to natural shampoo bars. However, folks with long hair may have to change their shampoo technique when switching from commercial liquid shampoo or synthetic detergent shampoo bars to natural bars.

    We have discovered that people with long hair often feel the need to use too much shampoo. Also, it is more difficult to rinse shampoo out of all the little nooks and crannies in long hair. As a result, there are pockets of soap residue left in the hair that make hair feel tacky.

    I have found that many times the proper technique makes all the difference.

    Natural Shampoo Bar Technique for Long HairI have long, fine hair. Below is my technique for using a shampoo bar.

    • thoroughly wet my hair
    • tie my long hair into a loose ponytail
    • wet the natural shampoo bar and rub the bar across only the top of my head in strokes from front to back until I have covered the entire scalp area (Rubbing any shampoo vigorously in all directions causes lots of tangles!)
    • massage my entire scalp (only the scalp) in a combing motion to work the lather through my hair
    • I do not rub the bar or work the lather on the length of my hair
    • take out my ponytail and rinse allowing the shampoo to drip down the length of my hair (I have found that this rinsing is enough to clean the length of my hair)
    • rinse, rinse, rinse for at LEAST one minute as I rub my fingers through my hair to be sure that all of the shampoo is rinsed away
    • squeeze gently on the length to remove excess water and cover with a towel while I dry off
    • I do not rub the towel over my wet hair because it causes nasty tangles
    • use a wide toothed comb and gently comb from the bottom up

    Dry and style your hair as usual!
