Frequently Asked Questions
Will conditioner make my fine hair greasy or flat?
Conditioner can weigh fine hair down if applied to the scalp or if it contains heavy oils/butters. To avoid greasiness, apply conditioner only to mid-lengths and ends, use a lightweight formula, rinse thoroughly, and consider clarifying once every 7–10 washes if you notice buildup.
How often should I condition thin, fine hair?
Most people with fine hair can condition every wash, focusing product on mid-lengths and ends. If your scalp gets oily quickly, try conditioning every other wash or use a lighter, rinse-out formula to preserve volume at the roots.
What ingredients help detangle without weight?
Look for lightweight humectants (glycerin), hydrolyzed proteins (keratin, plant proteins), sea kelp or coconut water for moisture, and light oils like chia seed oil. These provide slip and temporary strengthening without the heaviness of thick butters or heavy mineral oils.
Can I use a leave-in on fine hair?
Yes—choose a lightweight, spray or milk-style leave-in and apply to ends only. Avoid heavy creams near the roots. A light leave-in can improve detangling and heat protection without sacrificing volume.
