The Root Of It: How To Find The Best Shampoo For Sensitive Scalps
Here's how to keep your fragile scalp feeling nourished and calm.
As your scalp is an extension of the skin on your face, it's no wonder that it's prone to similar issues that your complexion may experience – whether that's acne, dandruff or congestion that requires a mild scrub.
For a long time, scalp care has fallen to the wayside in favour of products that spotlight glossy, voluminous hair. But a healthy scalp is the foundation of healthy hair growth, and it's important to take stock of how your scalp is feeling so you can provide it with the correct care and nourishment. If your scalp has been feeling a little sore and looking slightly red recently, or you're suddenly going through sudden onset of flaking, you may be experiencing scalp sensitivity.

What does a sensitive scalp look like?
Redness and a sore sensation are obvious telltale signs of an irritated scalp, but, as trichologist Hannah Gaboardi points out, dryness is also a symptom. 'It leads to flakiness that may resemble dandruff, along with a tight, uncomfortable feeling. Persistent itching is a common sign, and scratching can exacerbate the irritation, causing further redness or small wounds,' says Gaboardi who runs the Hair Growth Clinic at Nobu Hotel, Portman Square.
She adds: 'Some individuals experience a burning or stinging sensation, especially when using certain hair products or after exposure to sun or wind.' Bumps, pimples, or even blisters can also occur in severe cases, which may indicate an infection or allergic reaction. 'Prolonged sensitivity can sometimes lead to hair thinning or loss, typically due to inflammation affecting the hair follicles,' shares Gaboardi.
What causes sensitive scalps?
There are a myriad of reasons behind a fragile scalp. If you're prone to skin conditions such as psoriasis and eczema or have an underlying autoimmune disease, chances are, your scalp can be affected too. Sunburn, tight hairstyles, and allergic reactions to certain haircare products can also lead to a tender scalp. Adds Gaboardi: 'Stress, infections, and hormonal changes may increase scalp sensitivity, as well as nutritional deficiencies, particularly in vitamins and minerals like B vitamins, zinc, and iron.
How to manage sensitive scalps
If you suspect that a haircare ingredient is irritating your scalp, it's time to take it back to basics. Give your styling products a rest (especially those that are applied on the scalp), and switch to a simple shampoo.
'Look for mild, pH-balanced, and hypoallergenic formulas that are fragrance-free and sulphate-free. Natural ingredients like aloe vera, chamomile, and oatmeal can provide soothing effects, while anti-inflammatory ingredients such as tea tree oil or zinc pyrithione can help calm irritation,' shares Gaboardi. While most people can tolerate fragrance and sulphates (and they are generally safe to use), opting out can help you narrow down what's causing your sensitivity.
'Over-washing should be avoided as it can strip the scalp of its natural oils, leading to dryness and irritation,' she adds. 'Instead, wash your hair every few days with lukewarm water, and limit the use of heat styling tools. Gentle brushing with a soft-bristled brush and protecting your scalp from the sun can also help reduce irritation.'
When should you see a hair professional?
If your scalp flare-up persists or worsens (or if you notice new symptoms) over time despite these changes, do book in with a trichologist or your healthcare provider. As Gaboardi says, 'early intervention can prevent more serious issues and help manage your scalp health effectively.'
