Oily scalp: how to lighten the roots without damaging them?

It's a misconception that's still very widespread, especially among young girls: having oily roots means your hair is dirty . Wrong! Oil isn't dirt, it's simply sebum , a substance naturally produced by the scalp to protect the skin and hair. But when it's produced in excess, it can give a "heavy roots" effect, which is difficult to live with on a daily basis.

Overwashing makes things worse

When faced with this feeling of discomfort, the first instinct is often to wash your hair more frequently. And yet, this is exactly what you should avoid . By washing too often—and especially with formulas that are too harsh—we deprive the scalp of its natural protection. The result: it feels attacked… and reacts by producing even more sebum . This is what we call the rebound effect.

💡 What science says : Oily scalp is the result of an imbalance , not poor hygiene. Stress, hormones (puberty, menstrual cycle), or improper skincare can stimulate the sebaceous glands .

Understanding the real causes

Excess sebum is often linked to a period of hormonal changes , such as puberty or menstrual fluctuations. Stress also plays a role: it can unbalance the scalp microbiome, and therefore disrupt sebum regulation.

Furthermore, certain everyday actions can make the situation worse: overly vigorous massages, rubbing with a towel, water that is too hot, or even products containing aggressive sulfates.

The right actions to regulate gently

It's not about "stripping" to purify, but about supporting the natural regulation of the scalp . Here are the essential steps:

• Space out washes gradually (every 2 or 3 days at first).
  
• Choose a gentle, purifying shampoo , without sulfates or occlusive silicones.
  
• Rinse with warm or cool water to tighten cuticles.
  
• Massage the scalp gently , without rubbing.
  
• Avoid the roots when applying conditioner or mask.
  
  

💡 Selective Lady Tip : Adopt a gentle wash with the Purifying Detox Shampoo , formulated to cleanse without stripping. It respects the scalp's microbiome while eliminating excess sebum. Complete with a fresh rinse and a soothing massage: your scalp will regain balance and lightness.

In summary

Having oily roots doesn't mean your hair is dirty . It's a message your scalp is sending you, often to signal an imbalance. Over-washing, harsh products, or an unsuitable routine can make things worse. The solution? A gentle routine, targeted care, and time .

Take care of your scalp like you would your skin: with listening, patience and well-chosen products . Your roots will thank you.
