Hair, approached at the root
Why nutrition and stress belong in the hair conversation.
More hair in your brush can leave you wondering what changed. Stressful seasons and insufficient nutrients, including iron, can contribute to shedding or hair loss. The cause matters.

Explore the ingredients and research
Lustriva® Hair thickness support
A bonded arginine silicate and magnesium biotinate complex, studied at the follicle level for its effect on hair thickness. In a 12-week randomized, placebo-controlled study in women, the high-dose Lustriva group showed an improvement in measured hair thickness as early as week 3 versus placebo, maintained through week 12.†
KSM-66® Ashwagandha Stress support
Stress can trigger excessive hair shedding. TAJI includes KSM-66® Ashwagandha for healthy stress-response support.* A 2026 randomized trial also reported improvements in hair density, growth rate, and hair-cycle measurements after 75 days of oral KSM-66®. That trial used 600 mg daily; TAJI provides 300 mg daily, so its hair outcomes cannot be assumed for TAJI's dose. The study did not establish that TAJI reduces shedding.
Ferrochel® Chelated iron for nutritional support
Low iron can contribute to hair loss. TAJI provides 18 mg of iron per daily serving as Ferrochel®, a ferrous bisglycinate chelate studied for absorption and tolerability. Its role here is nutritional support; absorption research does not establish a direct reduction in shedding. If you suspect iron deficiency, speak with a healthcare professional about testing and appropriate treatment.

About the three-week finding
Kalman & Hewlings (2021) studied 90 women for 12 weeks. The high-dose group showed a significant change in the ratio of fine (vellus) to thicker (terminal) hairs versus placebo by week 3, maintained through week 12. This measurement does not establish a specific increase in hair length by three weeks.
The study's high-dose capsule contained 146.5 mg inositol-stabilized arginine silicate and 11.7 mg magnesium biotinate, providing 10 mg silicon and 10 mg biotin. The study was funded by JDS Therapeutics. TAJI's finished formula was not tested in this trial.

How to take TAJI

Keep TAJI wherever it fits naturally into your day.
Choose your supply →What to expect
Give your hair time.
If a nutrient deficiency is contributing to shedding, correcting it can help hair regrow. The timeline depends on the nutrient, how low your levels are, and whether the cause has been addressed.
Month 1
Start with a baseline
Take a starting photo of your part and hairline, and take TAJI as directed with food. If low nutrient levels are part of the picture, addressing them gives your hair the support it needs. Follow your clinician’s plan for any confirmed deficiency.
Months 2–3
Look for early changes
Keep taking photos in the same lighting and notice changes in shedding, your part, and short new hairs. As a deficiency is corrected, hair can begin to recover—visible progress follows your hair’s growth cycle.
Months 3–6+
Watch for regrowth
When a deficiency contributing to shedding has been corrected, new growth can become more noticeable over the following months. Give those new hairs time to grow: fuller-looking hair after temporary shedding often takes 6–9 months or longer.
This is general guidance for deficiency-related shedding, not a tested TAJI results schedule. TAJI supplies 18 mg iron per serving and may not be sufficient to treat a diagnosed deficiency. Hair regrowth guidance · Iron deficiency guidance

How do nutrition and stress relate to shedding?
Stress can trigger excessive shedding, and insufficient iron or other nutrients can contribute to hair loss. TAJI provides hair-thickness, nutritional, and healthy stress-response support.* Its ingredient roles do not mean every cause of shedding can be addressed with a supplement. If shedding is persistent or unexplained, speak with a healthcare professional.
Is TAJI just another biotin supplement?
No. TAJI is a multi-ingredient formula designed around several factors relevant to healthy hair, including nutritional status, stress support, and hair-thickness support. It combines 9 intentional ingredients rather than relying on biotin alone.*
Why does TAJI contain iron?
Iron is essential for normal red blood cell production and oxygen transport, and low iron has been associated with hair shedding in some research. TAJI includes Ferrochel®, a chelated iron form designed for absorption, as part of its broader nutritional support.
How long should I take TAJI?
We recommend giving your routine at least 90 days before evaluating meaningful changes in hair growth and thickness.
Can I take TAJI with my other vitamins?
TAJI contains several active ingredients, so check your total daily intake and speak with your healthcare professional if you're already taking supplements or medications.
Is TAJI only for Black women?
No. TAJI was created from an East African and diaspora perspective, but it is for adults of every background who want nutritional, stress, and hair-thickness support as part of their hair routine.*
Do I need to have an iron deficiency to take TAJI?
TAJI provides 18 mg of iron per daily serving. It is not intended to diagnose or treat iron deficiency. Speak with your healthcare professional before use if you have been advised to limit iron, have an iron-storage condition, or are unsure whether an iron-containing supplement is appropriate for you.
Can TAJI replace treatment for hair loss?
No. TAJI is a dietary supplement intended to support normal hair health and is not a treatment for medical hair-loss conditions. Sudden or unexplained hair loss should be evaluated by a healthcare professional.
Can I take it if I'm pregnant or breastfeeding?
Please consult your healthcare professional before using TAJI during pregnancy or breastfeeding.
Can TAJI interact with medications?
Iron can affect the absorption of certain medications, including levothyroxine and levodopa. If you take prescription medication or another iron-containing supplement, ask your healthcare professional how to use TAJI safely.
What if TAJI isn't right for me?
Contact us within 30 days of delivery. We'll listen, review your experience individually, and determine how we may be able to help. Because TAJI is an ingestible product, dissatisfaction with results does not automatically qualify an order for a refund, replacement, or store credit.
What's your return policy?
For health and safety reasons, TAJI is final sale and cannot be returned or refunded because it is an ingestible product. If your order arrives damaged, defective, or incorrect, contact us within 7 days of delivery with your order number and photographs so we can review the issue. Any replacement, store credit, or other accommodation is determined case by case and is not guaranteed. See our refund policy for complete terms.
