Scalp oiliness is determined by how much sebum your scalp produces, which is largely driven by genetics and hormones. Washing too often or too rarely both cause problems. This 8-question assessment identifies your scalp type and gives you a personalized wash frequency recommendation and shampoo ingredient guide.
Scalp Type Assessment
8 questions to identify your scalp type
How to Use the Scalp Oiliness Assessment
Understanding your scalp type is essential for choosing the right shampoo, wash frequency, and scalp treatments. Washing an oily scalp too infrequently leads to buildup and potential dandruff. Over-washing a dry scalp strips it of necessary moisture, triggering more oil production as compensation.
Step 1: Answer the Assessment Questions
Answer 8 questions about your scalp's typical behavior. Think about your scalp when you have not used dry shampoo or added any products — its natural state. Include questions about how your hair looks and feels 24, 48, and 72 hours after washing.
Step 2: Review Your Scalp Type
The quiz identifies six scalp types: very oily, oily, normal, combination (oily scalp/dry ends), dry, and very dry. Each type has different washing frequency needs. Most people fall into oily or combination, but genetic differences mean what works for one person may not work for another.
Step 3: Use the Ingredient Guide
Oily scalps benefit from clarifying shampoos with zinc pyrithione, salicylic acid, or tea tree oil. Dry scalps need moisturizing shampoos with glycerin, aloe vera, and ceramides. Combination scalps need a shampoo that cleanses well at the root without stripping the ends — apply conditioner from mid-shaft down only.
Step 4: Adjust Based on Results
If switching wash frequency, do so gradually. Going from daily to every other day may cause a 2-week adjustment period where the scalp overproduces oil before normalizing. Use dry shampoo to manage the transition period if needed. If scalp issues persist after adjusting your routine, consult a dermatologist.

Is my data private?

How often should I wash my hair if my scalp is oily?
Oily scalps typically need washing every 1-2 days. Very oily scalps may need daily washing, which is fine when using gentle, sulfate-free shampoos. Over-washing can stimulate sebum production temporarily, but this usually normalizes within 2-4 weeks of consistent washing with a gentle formula.
What causes an oily scalp?
Sebum (oil) production is primarily driven by genetics and hormones. Other contributing factors include diet high in refined carbohydrates and dairy, stress (which increases androgen hormones that trigger sebum production), hot and humid climates, heavy conditioner or styling product use on the scalp, and certain medications.
Can I have an oily scalp and dry hair ends?
Yes, combination scalp is very common. The scalp produces excess oil while the mid-lengths and ends are dry from lack of moisture transfer or styling damage. Use shampoo only on the scalp, and conditioner only on the mid-lengths and ends. Look for products specifically formulated for combination scalp types.
What shampoo ingredients help with an oily scalp?
Look for zinc pyrithione (anti-fungal, reduces sebum), salicylic acid (exfoliates scalp buildup), tea tree oil (anti-bacterial), and surfactants like sodium lauryl sulfate which cleanse deeply. Avoid silicones and heavy conditioning agents in shampoo if your scalp is oily.
Should I consult a dermatologist about my scalp?
Yes, if you experience significant scalp flaking, itching, redness, hair loss, or if your scalp condition does not improve with changes to your hair care routine, consult a dermatologist. Conditions like seborrheic dermatitis, psoriasis, or fungal infections require medical treatment.
