The Aryl hydrocarbon receptor (AHR) is a cytosolic receptor and ligand-activated transcription factor widely expressed across various cell types in the body. Its signaling is vital for host responses at barrier sites, regulating epithelial renewal, ...

May 26, 2020 · Dull hair tends to lack moisture, shine, and body. It can be caused by many factors, like using the wrong products, not getting enough nutrients in your diet, or overusing harsh chemicals...

The aryl hydrocarbon receptor (AHR) is a ligand-dependent transcription factor regulating adaptive and maladaptive responses toward exogenous and endogenous signals. Research from various biomedical disciplines has provided compelling evidence that ...

Aryl hydrocarbon receptor (AHR) was initially discovered as a cellular protein involved in mediating the detoxification of xenobiotic compounds. Extensive research in the past two decades has identified several families of physiological ligands and uncovered important functions of AHR in normal development and homeostasis.

May 8, 2018 · UV exposure can fade hair color—old news to anyone who color-treats her hair. But it may cause dullness even if you've never colored your hair. "UV and heat open the cuticle and break down...

Aug 18, 2021 · If you have dull hair, try switching your hair care products and routine. Avoid the use of harsh chemicals and styling tools on the hair, and quit smoking. If your hair stays dull even after proper care, consult a doctor as this may be indicative of an underlying medical condition.

AhR deletion and activation by the potent environmental toxicant, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), adversely impacted neurogenesis and cognition. Adult AhR-deficient mice exhibited impaired hippocampal-dependent contextual fear memory while hippocampal-independent memory remained intact.

Hair that lacks hydration and its natural luster is referred to as dull hair. When the hair doesn’t get or retain adequate moisture, dullness sets in. Dryness, frizz, and a harsh texture are all signs of dull hair.

Jul 1, 2023 · AhR is a ligand-driven receptor with intricate pharmacology of activation depending on the type and quantity of ligand present. Therefore, a better understanding of AhR ligands per se is critical to move the field forward.

Sep 27, 2024 · Common dull hair causes include: Product buildup: Over time, your hair and scalp may accumulate buildup and residue from shampoo and styling products. Eventually, that buildup can block natural hair oils from getting to the hair shaft – resulting in dull, dry hair.
