The tools, guides and other content on LJ Hair Lab are for general educational purposes. They are not medical advice and do not replace a consultation with a doctor, dermatologist or other qualified health professional.
- Our tools give estimates based on averages and the answers you provide. Your results may differ.
- We do not diagnose or treat hair loss, alopecia, scalp disease, allergies or any other condition.
- Chemical services such as relaxers, texturizers, color and bleach can injure the scalp and hair. Follow the manufacturer's instructions, do patch and strand tests, and use a licensed professional.
- Check ingredient lists yourself if you have allergies — formulas change and labels can differ by batch or country.
See a board-certified dermatologist if you notice bald patches, sudden heavy shedding, scalp pain, burning, sores, redness, scaling, or broken hairs and thinning around the hairline. If you think you have a medical emergency, call 911 or your local emergency number.
Never ignore professional advice or delay seeking it because of something you read on this site.
