Are you having these scalp problems? Itchy scalp, oily scalp or scalp acne? It's important to differentiate what is causing you these and what scalp treatments there are before it leads to more damaging concerns like hair loss!


What causes itchy scalp?

So, why does my scalp itch? An itchy scalp, or scalp pruritus, is a common problem that can cause frustrating symptoms, such as frequent scratching and discomfort.


  • Dandruff

The most common cause for itchy scalp is dandruff. While the exact cause for scalp dandruff is not definite, people with oily scalp types tend to be more prone to dandruff because Malassezia yeast thrive in oil.

Cause of Dandruff

This bacteria yeast leads to an accumulation of dead flaky skin, which is your body’s inflammatory response to an overgrowth of yeast. As a result, causing the itching and scalp redness at times.

Other causes for scalp with dandruff could be due to stress, or hormonal fluctuations.

  • Product buildup

Another one of the reasons for itchy scalp is product buildup. This can occur with hair styling products especially those containing silicone (eg hair conditioners or hair sprays) that can make your scalp itchy and irritated. Just imagine the layer of silicone sitting atop your scalp and trapping the dirt.

Product build-up can trap and lock in allergens, irritants close to your scalp. It also clogs your hair follicles. And the longer they are in contact with your scalp, the more likely it is they will be the cause of your itching.

Just in case you are thinking you can't do without your conditioners, try our highly reviewed "No Conditioner" Carediem Shampoo, that allows you to wash your hair, without the need to coat your hair after with toxic conditioners that contains silicones.

  • Contact Dermatitis

Do you have sensitive skin? Have you had any allergies reaction to skincare products in the past? If you can answer yes to any of these questions, your itching scalp may be caused by contact dermatitis, which is the same allergic reaction when your skin reacts to certain products that contains irritants or allergens to your scalp. You could also be allergic to certain ingredients in a shampoo, conditioner, or any other product that touches your scalp.

It is also common among people who dye their hair. Often the culprit is an ingredient in the dye called para-phenylenediamine (PPD), which is found in black hair dyes.

  • Ringworms & Head Lice

Ringworms is an infection caused by a fungus. If you get ringworm on your scalp, you’ll likely have a red itchy rash. Do seek a doctor for prescription medication to treat ringworm on the scalp.

You can also look out for signs of tiny bugs, as an itchy scalp could also be caused by head lice.


What causes scalp acne?

Scalp acne looks like small pimples or zits on the scalp. These pimples can be itchy and sore. Just like pimples on our skin, scalp acne occurs when hair follicles get clogged by dirt, bacteria and oil. When your sebaceous glands produce excess sebum, it can clog your pores and result in pimples on scalp.

Some other reasons why acne appear on scalp: stress, hormonal balances, and certain foods. Product buildup from oil-based products like heavy pomades can cause clogging of the pores, which makes cleaning your scalp with the right products even more important.


Is oily scalp the root of all problems?

So far, it seems that one of the main causes for itchy scalp and scalp acne is having an oilier scalp than usual. Well, a little oil is ok, as the sebum’s important role is to help protect healthy hair. But it is essential to keep your scalp cleansed.

However, oily scalps when left unmanaged, especially in hot and humid climates, tend to get even oilier. If too much sebum builds up on the scalp, it traps dead skin cells and dirt particles. This clogs up the hair follicles and can lead to scalp problems such as hair thinning, premature hair loss, itching and scalp acne. 

Not to mention, sebum from the scalp will also weigh down on your hair, making your hair looking flat and greasier to touch.


How to get rid of oily scalp & itchy scalp?

Use Cossu Scalp Detox as a DIY oily scalp treatment at home. It uses carbonic acid to gently exfoliate scalp and remove the serum and dirt that are clogged in your hair follicles. Scalps are also healthier when the pH levels are slightly acidic, as it helps reduce bacteria and fungi.

The more expensive option to help detox your scalp would be professional scalp treatment in Singapore. Most hair salons will steam the scalp to help loosen buildup, then they'll deep cleanse the entire scalp pores with scalp exfoliation products.

Avoid applying conditioner to the scalp. It makes your scalp greasy, promotes hair fall and bacterial growth. Instead of applying your conditioner all over, just apply from the ends of your hair and work upwards, avoiding the scalp entirely.


How to treat scalp with pimples?

We recommend washing your hair thoroughly to remove excess oil and hair care products that is build up in our clogged pores. In most cases, a doctor will recommend a scalp treatment or medicated scalp shampoo. These shampoos usually contain ingredients like

  • tea tree oil, an essential oil that helps eliminate bacteria on the scalp
  • salicylic acid, which helps to get rid of dead skin cells
  • glycolic acid, which can help exfoliate the scalp


Why scalp treatment important?

Can I just wash my hair with shampoo? Scalp treatments are important because it helps unclog and lifts oil and dead skin cells off the scalp more thoroughly than shampoo. Problems can arise if you don’t deal with the oil buildup, as it can cause scalp problems such as hair loss and itchy, flaky scalp conditions. Healthy hair begins at the scalp, so we should treat our hair like our skin and exfoliate our hair follicles regularly.


How often should a scalp treatment be given?

We recommend doing COSSU hair scalp treatment once or twice a week at home in the beginning to detox and get the dead skin under control. For oily scalp treatment and itchy scalp treatment, you may do so more often (2-3 times a week).

Following that, once you notice that your scalp oil is lesser, you can reduce it to three to four times a month. But if you have a scalp condition like scalp psoriasis, do consult a scalp specialist before starting your scalp care routine.

In conclusion, when it comes to removing your harmful chemicals, a scalp detox is the perfect alternative to help rebalance your scalp. It rids your hair of clogging buildup while nourishing the scalp.

It helps stimulate hair follicles, allowing for hair growth, and clears the scalp of oil, dandruff, and acne. When your hair follicles begin to flourish, you should see the difference in your hair texture within a week or two :)
