Side Effects Of Using Rosemary Water On Hair

side effects of rosemary water

Scalp Irritation

Rosemary water is generally safe for most people, but some individuals may experience scalp irritation after using it. This can manifest as redness, itchiness, or a burning sensation on the scalp. 

The herb’s potent compounds may be too strong for some sensitive scalps, leading to these discomforts. To minimize the risk of irritation, consider diluting rosemary water with plain water or a carrier oil before application. 

Additionally, perform a patch test on a small area of your scalp before using it more broadly to gauge your skin’s reaction.

Dryness and Frizziness

Rosemary water is known for its astringent properties, which can lead to dryness, especially for those with already dry hair. 

If you notice increased frizz or a lack of moisture after using rosemary water, consider reducing the frequency of its application or combining it with a moisturizing hair mask. 

Adding a few drops of essential oils like lavender or jojoba can also help counteract dryness, making your hair feel soft and manageable.

Allergic Reactions

Although rare, some individuals may be allergic to certain compounds present in rosemary. Allergic reactions can vary from mild skin irritation to more severe symptoms like swelling and difficulty breathing. 

It’s essential to be vigilant and attentive to any changes in your skin or respiratory system after using rosemary water. If you experience any signs of an allergic reaction, stop using it immediately and seek medical attention if needed.

Lightening of Hair Color

Regular use of rosemary water on your hair can have a subtle lightening effect, particularly for those with lighter hair colors. The herb contains natural bleaching agents that can gradually lift the hair’s pigment.

While this might be a desirable outcome for some, if you prefer to maintain your current hair color, limit the frequency of rosemary water application or opt for other hair care options.

Oily Hair

Rosemary water has stimulating properties that can increase blood circulation in the scalp, leading to heightened oil production. 

While this is beneficial for individuals with dry scalps, those with naturally oily hair might find it exacerbates their condition. If you have oily hair, use rosemary water in moderation or avoid applying it directly to the scalp, focusing instead on the hair strands.


Rosemary contains compounds that can make the skin more sensitive to sunlight, leading to an increased risk of sunburn and skin damage. 

If you frequently apply rosemary water to your hair and scalp, take extra precautions to protect your skin from excessive sun exposure. 

There are several sunblocks that are formulated especially for scalps and hair that you can use. Also you can wear a hat or a cap while going out in bright sunlight if you use rosemary water on a regular basis.

Not Suitable for Certain Conditions

Individuals with specific scalp or hair conditions, such as scalp psoriasis or severe dandruff, should be cautious when using rosemary water. The herb’s potent properties might exacerbate these conditions or interfere with prescribed treatments. 

If you have any pre-existing scalp conditions, consult with a dermatologist or healthcare professional before incorporating rosemary water into your hair care routine.

Always patch test before widespread use, dilute the rosemary water if needed, and listen to your body’s responses. 

If you experience any adverse effects, discontinue use immediately and seek professional advice if necessary. With proper caution and thoughtful application, you can enjoy the many benefits of rosemary water while keeping your hair healthy and vibrant.

Are There Any Benefits of Using Rosemary Water On Hair?

Why Do You Use Rosemary Water For Hair

There are several reasons why people choose to use rosemary water for their hair. One of the main reasons is the belief that rosemary water can promote hair growth. In fact, it is proven by research that it works just as well for increasing new hair growth as 2 percent minoxidil. (Panahi, Yunes et al. “Rosemary oil vs minoxidil 2% for the treatment of androgenetic alopecia: a randomized comparative trial.” Skinmed vol. 13,1 (2015): 15-21.)

Many individuals turn to this natural remedy in hopes of achieving longer, thicker, and healthier locks. Additionally, rosemary water is often used for its potential scalp benefits. 

It is believed to help balance the scalp’s oil production, which can be beneficial for those with oily or dry scalps. Rosemary water is also known for its soothing properties, making it a popular choice for individuals with scalp conditions like psoriasis.

Does Rosemary Water Really Help Increase Hair Growth

Rosemary water is often touted as a natural remedy for promoting hair growth, but does it really live up to the hype? While many individuals believe in its efficacy, it is important to understand that the scientific evidence supporting this claim is limited. 

There is no definitive research that proves rosemary water can significantly increase hair growth.

That being said, rosemary water may still have some benefits for your hair. It is known for its potential scalp benefits, such as balancing oil production and soothing properties. 

A healthy scalp is essential for promoting optimal hair growth. Additionally, rosemary water is a natural alternative to commercial hair products, appealing to those who prefer organic and chemical-free ingredients for their hair care routine.

While rosemary water may not be a miraculous solution for hair growth, it can still be a valuable addition to your hair care regimen.

Can I Leave Rosemary Water In My Hair Overnight Without Damaging Hair

Can I Leave Rosemary Water In My Hair Overnight Without Damaging Hair

Leaving rosemary water in your hair overnight may seem like a tempting idea, but it’s important to consider the potential effects before diving in. While rosemary water can have some benefits for your hair, there are factors to be aware of to avoid damaging your precious locks.

One concern is the drying effect that rosemary water can have on your hair. Leaving it in overnight without rinsing it out may lead to dry and brittle strands, especially if used excessively. Additionally, rosemary water may cause color-fading in treated hair over time.

Another aspect to consider is the potential for product build-up. If you continuously use rosemary water without thoroughly cleansing your hair, it can result in dull and lifeless-looking locks.

It’s also worth mentioning that rosemary water may not be compatible with all hair types. Fine hair may become weighed down, and already dry or damaged hair may experience increased dryness.

To ensure the best results and minimize the risk of damage, it’s advisable to use rosemary water in moderation and rinse it out after a certain period of time. Always listen to your hair’s needs and consult with a professional if you have any concerns.

It is always advisable to consult with a dermatologist or trichologist before using any new product on the scalp, especially if you have psoriasis.

When incorporating rosemary water into your scalp care routine, it is essential to ensure that it does not exacerbate your symptoms. Conduct a patch test to check for any adverse reactions and start with a small amount of rosemary water diluted in water or carrier oil. 

Monitor your scalp for any changes or irritations. If you notice any worsening of your psoriasis or dermatitis symptoms, discontinue use immediately and seek professional guidance.
