It typically appears two to three months after the weight loss begins. It’s usually reversible, and eating enough protein and iron while losing weight helps protect your hair. Key […] - [Sulfate-Free Shampoo: 6 Proven Facts Before You Switch](https://botanicalhairandscalp.com/sulfate-free-shampoo/): Quick Answer: Sulfate-free shampoo uses milder cleansing agents instead of sulfates like SLS and SLES. Sulfates aren’t dangerous, but they’re strong cleansers that can irritate sensitive scalps and strip dry hair. Sulfate-free formulas suit sensitive, dry or colour-treated hair well, while very oily scalps may still benefit from an occasional stronger wash. Key Takeaways: Sulfate-free […] - [Scalp Serum Ingredients: 7 Proven Tips for Reading a Label](https://botanicalhairandscalp.com/scalp-serum-ingredients/): Quick Answer: Scalp serum ingredients are listed on the label in descending order of concentration, so what appears near the top makes up most of the product. To judge a serum, check where the headline actives sit, whether the base is lightweight, whether fragrance is high up, and whether claims are backed by named evidence […] - [Female Pattern Hair Loss: 6 Proven Signs and What to Do](https://botanicalhairandscalp.com/female-pattern-hair-loss/): Quick Answer: Female pattern hair loss is gradual thinning across the crown and parting, driven by genetics and hormones, which often becomes more noticeable after menopause. The hairline usually stays intact while the parting widens. It’s common, progressive and manageable — and early diagnosis gives you the most options to preserve density. Key Takeaways: Female […] - [Ferritin and Hair Loss: 5 Proven Facts About Low Iron](https://botanicalhairandscalp.com/ferritin-and-hair-loss/): QUICK ANSWER: Ferritin and hair loss are closely linked because ferritin measures your body’s iron stores, and hair is one of the first things deprioritised when iron runs low. Low ferritin is one of the most common and most treatable causes of thinning in women — and it can exist even when a standard blood […] - [Buildup: 7 Proven Signs and How to Clear It](https://botanicalhairandscalp.com/scalp-buildup/): QUICK ANSWER: Scalp buildup is the accumulation of product residue, natural oils, dead skin and hard-water minerals on the scalp. It leaves hair dull, heavy and limp, and can make the scalp itchy or flaky. A periodic gentle clarifying wash clears it — daily harsh washing doesn’t, and often makes things worse. Key Takeaways: Scalp […] - [Microbiome: 6 Proven Ways to Restore Balance](https://botanicalhairandscalp.com/scalp-microbiome/): Quick Answer The scalp microbiome is the community of bacteria and fungi living on your scalp skin. When it’s balanced, the scalp is calm and comfortable; when it’s disrupted — often by over-washing, harsh products or excess oil — you can get flaking, itching and irritation. Restoring balance means gentler cleansing, not harsher. Key Takeaways: […] - [Thyroid Hair Loss: 6 Proven Signs It Isn't Just Menopause](https://botanicalhairandscalp.com/thyroid-hair-loss/): Quick Answer:Thyroid hair loss causes diffuse, all-over thinning that looks almost identical to menopausal thinning, and the wider symptoms overlap too. The only reliable way to tell them apart is a blood test. If you’re losing hair in midlife, ask your GP to check thyroid function alongside iron, ferritin and vitamin D. Key Takeaways: Thyroid […] - [Sleep and Hair Loss: 6 Proven Connections Worth Knowing](https://botanicalhairandscalp.com/sleep-and-hair-loss/): QUICK ANSWER Poor sleep and hair loss can occur together, but current evidence does not show that a few bad nights—or poor sleep by itself—directly causes permanent hair loss. Sleep loss can interact with stress, menopause symptoms, illness and daily habits, while significant physical or emotional stress is a recognised trigger for temporary diffuse shedding […] - [Rosemary Oil for Hair: 5 Proven Facts and Safe Use](https://botanicalhairandscalp.com/rosemary-oil-for-hair/): QUICK ANSWER Rosemary oil has limited but notable human evidence. In a 2015 single-blind randomised trial, 100 men with androgenetic alopecia used rosemary oil or 2% minoxidil for six months. Hair counts increased in both groups at six months, with no significant difference between groups; scalp itching was reported more often with minoxidil. The study […] - [How Often to Wash Hair: 6 Proven Rules for Midlife](https://botanicalhairandscalp.com/how-often-to-wash-hair/): QUICK ANSWER: How often to wash hair depends on how quickly your scalp becomes oily or dirty, your hair texture, your activity level, styling-product use and any scalp condition. Fine, straight hair with an oily scalp may need shampooing daily or every other day, while dry, thick, curly or coily hair often needs washing much […] - [HRT and Hair Loss: 5 Proven Facts About Menopausal Thinning](https://botanicalhairandscalp.com/hrt-and-hair-loss/): QUICK ANSWER Menopause can affect hair density, diameter and texture, but HRT is not a hair-loss treatment and should not be started for hair symptoms alone. Research supports a biological link between changing hormones and the hair follicle, yet direct evidence that HRT reliably regrows scalp hair is limited. If your hair is thinning, the […] - [The Stress–Shedding Loop: How to Stop the Anxiety That's Making Your Hair Fall](https://botanicalhairandscalp.com/stress-and-hair-loss/): QUICK ANSWER Significant physical or emotional stress can trigger diffuse shedding known as telogen effluvium, often around three months later. The shedding itself can be distressing. Recovery usually depends on identifying and addressing the trigger, allowing time for the hair cycle to reset, and getting medical advice when loss is persistent, patchy or otherwise unusual. […] - [Telogen Effluvium 101: Why You're Suddenly Shedding (and When It Stops)](https://botanicalhairandscalp.com/telogen-effluvium/): QUICK ANSWER Telogen effluvium is diffuse hair shedding that occurs when illness, surgery, childbirth, emotional stress, marked weight loss or another trigger disturbs the normal hair cycle. Shedding commonly becomes noticeable around three months later. Acute telogen effluvium usually improves after the trigger resolves, although density takes longer to return. KEY TAKEAWAYS Let me start […] - [Solving the Greasy Scalp Dilemma: Why Your Serum Might Be Ruining Your Style](https://botanicalhairandscalp.com/greasy-scalp/): QUICK ANSWER A scalp that looks greasy soon after washing may reflect normal sebum production, product or conditioner left near the roots, an ineffective wash, or a scalp condition such as dandruff or seborrhoeic dermatitis. There is little evidence that washing itself makes sebaceous glands “rebound” by producing extra oil. Use a mild shampoo as […] - [The One-Minute Scalp Ritual: Treat Your Scalp Without Adding Time or Grease](https://botanicalhairandscalp.com/one-minute-scalp-ritual/): QUICK ANSWER A one-minute scalp ritual means applying a small amount of a lightweight, leave-in cosmetic scalp product along a few parting lines, then massaging gently with your fingertips. It can be a convenient way to care for scalp comfort without adding a rinse step or coating the lengths. It is not a treatment for […] - [Seaweed for Scalp Health: The Minerals Your Hair Follicles May Be Missing](https://botanicalhairandscalp.com/seaweed-for-scalp-health/): QUICK ANSWER Seaweed extracts can be useful cosmetic ingredients for scalp care because some provide film-forming, humectant, emollient or antioxidant compounds. That may help a well-formulated product condition dry or uncomfortable skin. However, the presence of minerals in seaweed does not mean those minerals are absorbed through the scalp in nutritionally meaningful amounts, and there […] - [How to “Wake Up” Your Scalp: Ginkgo, Microcirculation and Follicle Health](https://botanicalhairandscalp.com/ginkgo-biloba-for-hair/): QUICK ANSWER Ginkgo biloba is used in some scalp products because it has vascular and antioxidant effects in laboratory research. However, no convincing human trial shows that topical or oral ginkgo treats scalp hair loss. Mouse studies are interesting but preliminary, so ginkgo is best viewed as an optional cosmetic ingredient—not a way to “wake” […] - [The Oestrogen Drop: How Menopause Changes Your Scalp Oil and Hair Density](https://botanicalhairandscalp.com/menopause-hair-thinning-scalp-oil/): Quick Answer Hair thinning can become more noticeable around perimenopause and menopause, but a newly oily scalp and reduced hair density are not automatically one hormonal problem. Menopause may contribute to changes in the hair cycle and fibre diameter, while female-pattern hair loss, temporary shedding, ageing, genetics, illness, nutrition, medication and scalp conditions can overlap. […] - [Why Your Hair Texture Changes at 45: The Perimenopause Shift Explained](https://botanicalhairandscalp.com/perimenopause-hair-changes/): Quick Answer Hair thinning or hair loss can occur during perimenopause, but there is no single “menopause hair-loss” mechanism or pattern. Ageing, changing hormone levels, genetic susceptibility, female-pattern hair loss and temporary shedding can overlap. A gradually widening parting suggests female-pattern hair loss; sudden, heavy, patchy or painful loss needs medical assessment. Cosmetic care can […] ## Pages - [Kartee Munusamy](https://botanicalhairandscalp.com/kartee-munusamy/): Kartee Munusamy Founder and London salon professional Kartee Munusamy is an experienced London salon professional with thirty years behind the chair in Colliers Wood.
